### What changes were proposed in this pull request?
Improve the error message in test GroupedMapInPandasTests.test_grouped_over_window_with_key to show the incorrect values.
### Why are the changes needed?
This test failure has come up often in Arrow testing because it tests a struct with timestamp values through a Pandas UDF. The current error message is not helpful as it doesn't show the incorrect values, only that it failed. This change will instead raise an assertion error with the incorrect values on a failure.
Before:
```
======================================================================
FAIL: test_grouped_over_window_with_key (pyspark.sql.tests.test_pandas_grouped_map.GroupedMapInPandasTests)
----------------------------------------------------------------------
Traceback (most recent call last):

AssertionError: False is not true
```
After:
```
======================================================================

### What changes were proposed in this pull request?
In https://issues.apache.org/jira/browse/SPARK-29283, we only show the error message of root cause to end-users through JDBC client. In some cases, it erases the straightaway messages that we intentionally make to help them for better understanding.
The root cause is somehow obscure for JDBC end-users who only writing SQL queries.
e.g
```
Error running query: org.apache.spark.sql.AnalysisException: The second argument of 'date_sub' function needs to be an integer.;
```
is better than just
```
Caused by: java.lang.NumberFormatException: invalid input syntax for type numeric: 1.2
```
We should do as Hive does in https://issues.apache.org/jira/browse/HIVE-14368
In general, this PR partially reverts SPARK-29283, ports HIVE-14368, and improves test coverage
### Why are the changes needed?
1. Do the same as Hive 2.3 and later for getting an error message in ThriftCLIService.GetOperationStatus
2. The root cause is somehow obscure for JDBC end-users who only writing SQL queries.
3. Consistency with `spark-sql` script
### Does this PR introduce _any_ user-facing change?
Yes, when running queries using thrift server and an error occurs, you will get the full stack traces instead of only the message of the root cause
### How was this patch tested?

## What changes were proposed in this pull request?
When a Spark Job launched in Cluster mode with Yarn, Application Master sets spark.ui.port port to 0 which means Driver's web UI gets any random port even if we want to explicitly set the Port range for Driver's Web UI
## Why are the changes needed?
We access Spark Web UI via Knox Proxy, and there are firewall restrictions due to which we can not access Spark Web UI since Web UI port range gets random port even if we set explicitly.
This Change will check if there is a specified port range explicitly mentioned so that it does not assign a random port.

2. should consider data source options when inferring schema for file source
3. should consider data source options when getting the qualified path in file source v2.
### Why are the changes needed?
We didn't catch these issues in https://github.com/apache/spark/pull/28760, because the test case is to check error when initializing the file system. If we initialize the file system multiple times during a simple read/write action, the test case actually only test the first time.

### What changes were proposed in this pull request?
Spark can't push down scan predicate condition of **Or**:
Such as if I have a table `default.test`, it's partition col is `dt`,
If we use query :
```
select * from default.test
where dt=20190625 or (dt = 20190626 and id in (1,2,3) )
```
In this case, Spark will resolve **Or** condition as one expression, and since this expr has reference of "id", then it can't been push down.
Base on pr https://github.com/apache/spark/pull/28733, In my PR , for SQL like
`select * from default.test`
`where dt = 20190626 or (dt = 20190627 and xxx="a") `
For this condition `dt = 20190626 or (dt = 20190627 and xxx="a" )`, it will been converted to CNF
```
(dt = 20190626 or dt = 20190627) and (dt = 20190626 or xxx = "a" )
```
then condition `dt = 20190626 or dt = 20190627` will be push down when partition pruning

fix error exception messages during exceptions on Union and set operations
### Why are the changes needed?
Union and set operations can only be performed on tables with the compatible column types,while when we have more than two column, the exception messages will have wrong column index.
Steps to reproduce:
```
drop table if exists test1;
drop table if exists test2;
drop table if exists test3;
create table if not exists test1(id int, age int, name timestamp);
create table if not exists test2(id int, age timestamp, name timestamp);
create table if not exists test3(id int, age int, name int);
insert into test1 select 1,2,'2020-01-01 01:01:01';
insert into test2 select 1,'2020-01-01 01:01:01','2020-01-01 01:01:01';
insert into test3 select 1,3,4;
```
Query1:
```sql
select * from test1 except select * from test2;
```
Result1:
```
Error: org.apache.spark.sql.AnalysisException: Except can only be performed on tables with the compatible column types. timestamp <> int at the second column of the second table;; 'Except false :- Project [id#620, age#621, name#622] : +- SubqueryAlias `default`.`test1` : +- HiveTableRelation `default`.`test1`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#620, age#621, name#622] +- Project [id#623, age#624, name#625] +- SubqueryAlias `default`.`test2` +- HiveTableRelation `default`.`test2`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#623, age#624, name#625] (state=,code=0)
```
Query2:
```sql
select * from test1 except select * from test3;
```
Result2:
```
Error: org.apache.spark.sql.AnalysisException: Except can only be performed on tables with the compatible column types
int <> timestamp at the 2th column of the second table;
```
the above query1 has the right exception message
the above query2 have the wrong errors information, it may need to change to the following
```
Error: org.apache.spark.sql.AnalysisException: Except can only be performed on tables with the compatible column types.
int <> timestamp at the third column of the second table

### What changes were proposed in this pull request?
Modify the example for `timestamp_seconds` and replace `collect()` by `show()`.
### Why are the changes needed?
The SQL config `spark.sql.session.timeZone` doesn't influence on the `collect` in the example. The code below demonstrates that:
```
$ export TZ="UTC"
```
```python
>>> from pyspark.sql.functions import timestamp_seconds
>>> spark.conf.set("spark.sql.session.timeZone", "America/Los_Angeles")
>>> time_df = spark.createDataFrame([(1230219000,)], ['unix_time'])
>>> time_df.select(timestamp_seconds(time_df.unix_time).alias('ts')).collect()
[Row(ts=datetime.datetime(2008, 12, 25, 15, 30))]
```
The expected time is **07:30 but we get 15:30**.

### What changes were proposed in this pull request?
When loading DataFrames from JDBC datasource with Kerberos authentication, remote executors (yarn-client/cluster etc. modes) fail to establish a connection due to lack of Kerberos ticket or ability to generate it.
This is a real issue when trying to ingest data from kerberized data sources (SQL Server, Oracle) in enterprise environment where exposing simple authentication access is not an option due to IT policy issues.
In this PR I've added Oracle support.
What this PR contains:
* Added `OracleConnectionProvider`
* Added `OracleConnectionProviderSuite`
### Why are the changes needed?
Missing JDBC kerberos support.
### Does this PR introduce _any_ user-facing change?
Yes, now user is able to connect to Oracle using kerberos.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR fixes a typo for a configuration property in the `spark-standalone.md`.
`spark.driver.resourcesfile` should be `spark.driver.resourcesFile`.
I look for similar typo but this is the only typo.
### Why are the changes needed?
The property name is wrong.
### Does this PR introduce _any_ user-facing change?
Yes. The property name is corrected.
### How was this patch tested?
I confirmed the spell of the property name is the correct from the property name defined in o.a.s.internal.config.package.scala.

### What changes were proposed in this pull request?
`formatDate` in utils.js `org/apache/spark/ui/static/utils.js` is partly refactored.
### Why are the changes needed?
In branch-2.4，task launch time is returned as html string from driver,
while in branch-3.x，this is returned in JSON Object as`Date`type from `org.apache.spark.status.api.v1.TaskData`
Due to：
LaunchTime from jersey server in spark driver is correct, which will be converted to date string like `2020-06-28T02:57:42.605GMT` in json object, then the formatDate in utils.js treat it as date.split(".")[0].replace("T", " ").
So `2020-06-28T02:57:42.605GMT` will be converted to `2020-06-28 02:57:42`, but correct is `2020-06-28 10:57:42` in GMT+8 timezone.

### What changes were proposed in this pull request?
This patch fixes the missed spot - the test initializes FileStreamSinkLog with its "output" directory instead of "metadata" directory, hence the verification against sink log was no-op.
### Why are the changes needed?
Without the fix, the verification against sink log was no-op.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Checked with debugger in test, and verified `allFiles()` returns non-zero entries. (It returned zero entry, as there's no metadata.)

### What changes were proposed in this pull request?
This PR add unlimited MATCHED and NOT MATCHED clauses in MERGE INTO statement.
### Why are the changes needed?
Now the MERGE INTO syntax is,
```
MERGE INTO [db_name.]target_table [AS target_alias]
USING [db_name.]source_table [<time_travel_version>] [AS source_alias]
ON <merge_condition>
[ WHEN MATCHED [ AND <condition> ] THEN <matched_action> ]
[ WHEN MATCHED [ AND <condition> ] THEN <matched_action> ]
[ WHEN NOT MATCHED [ AND <condition> ] THEN <not_matched_action> ]
```
It would be nice if we support unlimited MATCHED and NOT MATCHED clauses in MERGE INTO statement, because users may want to deal with different "AND <condition>"s, the result of which just like a series of "CASE WHEN"s. The expected syntax looks like
```
MERGE INTO [db_name.]target_table [AS target_alias]
USING [db_name.]source_table [<time_travel_version>] [AS source_alias]
ON <merge_condition>
[when_matched_clause [, ...]]
[when_not_matched_clause [, ...]]
```
where when_matched_clause is
```
WHEN MATCHED [ AND <condition> ] THEN <matched_action>
```
and when_not_matched_clause is
```
WHEN NOT MATCHED [ AND <condition> ] THEN <not_matched_action>
```
matched_action can be one of
```
DELETE
UPDATE SET * or
UPDATE SET col1 = value1 [, col2 = value2, ...]
```
and not_matched_action can be one of
```
INSERT *
INSERT (col1 [, col2, ...]) VALUES (value1 [, value2, ...])
```

### What changes were proposed in this pull request?
This patch proposes to coalesce partitions for repartition by expressions without specifying number of partitions, when AQE is enabled.
### Why are the changes needed?
When repartition by some partition expressions, users can specify number of partitions or not. If the number of partitions is specified, we should not coalesce partitions because it breaks user expectation. But if without specifying number of partitions, AQE should be able to coalesce partitions as other shuffling.
### Does this PR introduce _any_ user-facing change?
Yes. After this change, if users don't specify the number of partitions when repartitioning data by expressions, AQE will coalesce partitions.

### What changes were proposed in this pull request?
This PR fix `UserDefinedType.equal()` by comparing the UDT class instead of checking `acceptsType()`.
### Why are the changes needed?
It's weird that equality comparison between two UDT types can have different result by switching the order:
```scala

val udt1 = new ExampleBaseTypeUDT
val udt2 = new ExampleSubTypeUDT
println(udt1 == udt2) // true
println(udt2 == udt1) // false
```
### Does this PR introduce _any_ user-facing change?
Yes.

val udt1 = new ExampleBaseTypeUDT
val udt2 = new ExampleSubTypeUDT
println(udt1 == udt2) // true
println(udt2 == udt1) // false
```
After:
```scala
// ExampleSubTypeUDT.userClass is a subclass of ExampleBaseTypeUDT.userClass

### What changes were proposed in this pull request?
**First**
`DAGSchedulerSuite` provides `completeNextStageWithFetchFailure` to make all tasks in non first stage occur `FetchFailed`.
But many test case uses complete directly as follows:
```scala
complete(taskSets(1), Seq(
(FetchFailed(makeBlockManagerId("hostA"),
shuffleDep1.shuffleId, 0L, 0, 0, "ignored"), null)))
```
We need to reuse `completeNextStageWithFetchFailure`.
**Second**
`DAGSchedulerSuite` also check the results show below:
```scala
complete(taskSets(0), Seq((Success, 42)))
assert(results === Map(0 -> 42))
```
We can extract it as a generic method of `checkAnswer`.
### Why are the changes needed?

### What changes were proposed in this pull request?
Add American timezone during timestamp_seconds doctest
### Why are the changes needed?
`timestamp_seconds` doctest in `functions.py` used default timezone to get expected result
For example:
```python
>>> time_df = spark.createDataFrame([(1230219000,)], ['unix_time'])
>>> time_df.select(timestamp_seconds(time_df.unix_time).alias('ts')).collect()
[Row(ts=datetime.datetime(2008, 12, 25, 7, 30))]
```
But when we have a non-american timezone, the test case will get different test result.
For example, when we set current timezone as `Asia/Shanghai`, the test result will be
```
[Row(ts=datetime.datetime(2008, 12, 25, 23, 30))]
```
So no matter where we run the test case ,we will always get the expected permanent result if we set the timezone on one specific area.

### What changes were proposed in this pull request?
This pull request fixes a bug present in the csv type inference.
We have problems when we have different types in the same column.
**Previously:**
```
$ cat /example/f1.csv
col1
43200000
true
spark.read.csv(path="file:///example/*.csv", header=True, inferSchema=True).show()
+----+
|col1|
+----+
|null|
|true|
+----+
root
|-- col1: boolean (nullable = true)
```
**Now**
```
spark.read.csv(path="file:///example/*.csv", header=True, inferSchema=True).show()
+-------------+
|col1 |
+-------------+
|43200000 |
|true |
+-------------+
root
|-- col1: string (nullable = true)
```
Previously the hierarchy of type inference is the following:
> IntegerType
> > LongType
> > > DecimalType
> > > > DoubleType
> > > > > TimestampType
> > > > > > BooleanType
> > > > > > > StringType
So, when, for example, we have integers in one column, and the last element is a boolean, all the column is inferred as a boolean column incorrectly and all the number are shown as null when you see the data
We need the following hierarchy. When we have different numeric types in the column it will be resolved correctly. And when we have other different types it will be resolved as a String type column
> IntegerType
> > LongType
> > > DecimalType
> > > > DoubleType
> > > > > StringType
> TimestampType
> > StringType
> BooleanType
> > StringType
> StringType

### What changes were proposed in this pull request?
When you use floats are index of pandas, it creates a Spark DataFrame with a wrong results as below when Arrow is enabled:
```bash
./bin/pyspark --conf spark.sql.execution.arrow.pyspark.enabled=true
```
```python
>>> import pandas as pd
>>> spark.createDataFrame(pd.DataFrame({'a': [1,2,3]}, index=[2., 3., 4.])).show()
+---+
| a|
+---+
| 1|
| 1|
| 2|
+---+
```
This is because direct slicing uses the value as index when the index contains floats:
```python
>>> pd.DataFrame({'a': [1,2,3]}, index=[2., 3., 4.])[2:]
a
2.0 1
3.0 2
4.0 3
>>> pd.DataFrame({'a': [1,2,3]}, index=[2., 3., 4.]).iloc[2:]
a
4.0 3
>>> pd.DataFrame({'a': [1,2,3]}, index=[2, 3, 4])[2:]
a
4 3
```
This PR proposes to explicitly use `iloc` to positionally slide when we create a DataFrame from a pandas DataFrame with Arrow enabled.
FWIW, I was trying to investigate why direct slicing refers the index value or the positional index sometimes but I stopped investigating further after reading this https://pandas.pydata.org/pandas-docs/stable/getting_started/10min.html#selection
> While standard Python / Numpy expressions for selecting and setting are intuitive and come in handy for interactive work, for production code, we recommend the optimized pandas data access methods, `.at`, `.iat`, `.loc` and `.iloc`.
