## What changes were proposed in this pull request?
In the PR, I propose to switch the `DateFormatClass`, `ToUnixTimestamp`, `FromUnixTime`, `UnixTime` on java.time API for parsing/formatting dates and timestamps. The API has been already implemented by the `Timestamp`/`DateFormatter` classes. One of benefit is those classes support parsing timestamps with microsecond precision. Old behaviour can be switched on via SQL config: `spark.sql.legacy.timeParser.enabled` (`false` by default).
## How was this patch tested?
It was tested by existing test suites - `DateFunctionsSuite`, `DateExpressionsSuite`, `JsonSuite`, `CsvSuite`, `SQLQueryTestSuite` as well as PySpark tests.
Closes#23358 from MaxGekk/new-time-cast.

## What changes were proposed in this pull request?
An input without valid JSON tokens on the root level will be treated as a bad record, and handled according to `mode`. Previously such input was converted to `null`. After the changes, the input is converted to a row with `null`s in the `PERMISSIVE` mode according the schema. This allows to remove a code in the `from_json` function which can produce `null` as result rows.
## How was this patch tested?
It was tested by existing test suites. Some of them I have to modify (`JsonSuite` for example) because previously bad input was just silently ignored. For now such input is handled according to specified `mode`.

Following [SPARK-26024](https://issues.apache.org/jira/browse/SPARK-26024), I noticed the number of elements in each partition after repartitioning using `df.repartitionByRange` can vary for the same setup:
```scala
// Shuffle numbers from 0 to 1000, and make a DataFrame
val df = Random.shuffle(0.to(1000)).toDF("val")
// Repartition it using 3 partitions
// Sum up number of elements in each partition, and collect it.
// And do it several times
for (i <- 0 to 9) {
var counts = df.repartitionByRange(3, col("val"))
.mapPartitions{part => Iterator(part.size)}
.collect()
println(counts.toList)
}
// -> the number of elements in each partition varies
```
This is expected as for performance reasons this method uses sampling to estimate the ranges (with default size of 100). Hence, the output may not be consistent, since sampling can return different values. But documentation was not mentioning it at all, leading to misunderstanding.
## What changes were proposed in this pull request?
Update the documentation (Spark & PySpark) to mention the impact of `spark.sql.execution.rangeExchange.sampleSizePerPartition` on the resulting partitioned DataFrame.

This PR proposes to bump up the minimum versions of R from 3.1 to 3.4.
R version. 3.1.x is too old. It's released 4.5 years ago. R 3.4.0 is released 1.5 years ago. Considering the timing for Spark 3.0, deprecating lower versions, bumping up R to 3.4 might be reasonable option.
It should be good to deprecate and drop < R 3.4 support.

Closes#21649 from huaxingao/spark-23648.
Continuation of #22370. Summary of discussion there:
There is some inconsistency in the R manual w.r.t. supercedent functions linking back to deprecated functions.
- `createOrReplaceTempView` and `createTable` both link back to functions which are deprecated (`registerTempTable` and `createExternalTable`, respectively)
- `sparkR.session` and `dropTempView` do _not_ link back to deprecated functions
This PR takes the view that it is preferable _not_ to link back to deprecated functions, and removes these references from `?createOrReplaceTempView` and `?createTable`.
As `registerTempTable` was included in the `SparkDataFrame functions` `family` of functions, other documentation pages which included a link to `?registerTempTable` will similarly be altered.

A few SQL tests for R were failing in my development environment. In this PR, i am attempting to
address some of them. Below are the reasons for the failure.
- The catalog api tests assumes catalog artifacts named "foo" to be non existent. I think name such as foo and bar are common and i use it frequently. I have changed it to a string that i hope is less likely to collide.
- One test assumes that we only have one database in the system. I had more than one and it caused the test to fail. I have changed that check.
- One more test which compares two timestamp values fail - i am debugging this now. I will send it as a followup - may be.

## What changes were proposed in this pull request?
Fixing typos is sometimes very hard. It's not so easy to visually review them. Recently, I discovered a very useful tool for it, [misspell](https://github.com/client9/misspell).
This pull request fixes minor typos detected by [misspell](https://github.com/client9/misspell) except for the false positives. If you would like me to work on other files as well, let me know.

## What changes were proposed in this pull request?
during my travails in porting spark builds to run on our centos worker, i managed to recreate (as best i could) the centos environment on our new ubuntu-testing machine.
while running my initial builds, lintr was crashing on some extraneous spaces in test_basic.R (see: https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-sbt-hadoop-2.6-ubuntu-test/862/console)
after removing those spaces, the ubuntu build happily passed the lintr tests.
## How was this patch tested?
i then tested this against a modified spark-master-test-sbt-hadoop-2.6 build (see https://amplab.cs.berkeley.edu/jenkins/view/RISELab%20Infra/job/testing-spark-master-test-with-updated-R-crap/4/), which scp'ed a copy of test_basic.R in to the repo after the git clone. everything seems to be working happily.

The lint failure bugged me:
```R
R/SQLContext.R:715:97: style: Trailing whitespace is superfluous.
#' file-based streaming data source. \code{timeZone} to indicate a timezone to be used to
^
tests/fulltests/test_streaming.R:239:45: style: Commas should always have a space after.
expect_equal(times[order(times$eventTime),][1, 2], 2)
^
lintr checks failed.
```
and I actually saw https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-sbt-hadoop-2.6-ubuntu-test/500/console too. If I understood correctly, there is a try about moving to Unbuntu one.
## How was this patch tested?

lintr checks passed.

## What changes were proposed in this pull request?
Seems R's substr API treats Scala substr API as zero based and so subtracts the given starting position by 1.
Because Scala's substr API also accepts zero-based starting position (treated as the first element), so the current R's substr test results are correct as they all use 1 as starting positions.
## How was this patch tested?
Modified tests.

## What changes were proposed in this pull request?
https://github.com/apache/spark/pull/18944 added one patch, which allowed a spark session to be created when the hive metastore server is down. However, it did not allow running any commands with the spark session. This brings troubles to the user who only wants to read / write data frames without metastore setup.
## How was this patch tested?
Added some unit tests to read and write data frames based on the original HiveMetastoreLazyInitializationSuite.

A fix to https://issues.apache.org/jira/browse/SPARK-21727, "Operating on an ArrayType in a SparkR DataFrame throws error"
## How was this patch tested?
- Ran tests at R\pkg\tests\run-all.R (see below attached results)
- Tested the following lines in SparkR, which now seem to execute without error:
```
indices <- 1:4
myDf <- data.frame(indices)
myDf$data <- list(rep(0, 20))
mySparkDf <- as.DataFrame(myDf)
collect(mySparkDf)
```

Since all CRAN checks go through the same machine, if there is an older partial download or partial install of Spark left behind the tests fail. This PR overwrites the install files when running tests. This shouldn't affect Jenkins as `SPARK_HOME` is set when running Jenkins tests.

This is a followup to reduce AppVeyor test time. This PR proposes to reduce the number of shuffle partitions to reduce the tasks running R workers in few particular tests.
The symptom is similar as described in `https://github.com/apache/spark/pull/19722`. There are many R processes newly launched on Windows without forking and it makes the differences of elapsed time between Linux and Windows.
Here is the simple comparison for before/after of this change. I manually tested this by disabling `spark.sparkr.use.daemon`. Disabling it resembles the tests on Windows:
**Before**
<img width="672" alt="2017-11-25 12 22 13" src="https://user-images.githubusercontent.com/6477701/33217949-b5528dfa-d17d-11e7-8050-75675c39eb20.png">
**After**
<img width="682" alt="2017-11-25 12 32 00" src="https://user-images.githubusercontent.com/6477701/33217958-c6518052-d17d-11e7-9f8e-1be21a784559.png">
So, this probably will reduce roughly more than 10 minutes.
