zhoukang 8b69b17f3f [SPARK-21544][DEPLOY][TEST-MAVEN] Tests jar of some module should not upload twice 
## What changes were proposed in this pull request?

**For moudle below:**
common/network-common
streaming
sql/core
sql/catalyst
**tests.jar will install or deploy twice.Like:**
`[DEBUG] Installing org.apache.spark:spark-streaming_2.11/maven-metadata.xml to /home/mi/.m2/repository/org/apache/spark/spark-streaming_2.11/maven-metadata-local.xml
[INFO] Installing /home/mi/Work/Spark/scala2.11/spark/streaming/target/spark-streaming_2.11-2.1.0-mdh2.1.0.1-SNAPSHOT-tests.jar to /home/mi/.m2/repository/org/apache/spark/spark-streaming_2.11/2.1.0-mdh2.1.0.1-SNAPSHOT/spark-streaming_2.11-2.1.0-mdh2.1.0.1-SNAPSHOT-tests.jar
[DEBUG] Skipped re-installing /home/mi/Work/Spark/scala2.11/spark/streaming/target/spark-streaming_2.11-2.1.0-mdh2.1.0.1-SNAPSHOT-tests.jar to /home/mi/.m2/repository/org/apache/spark/spark-streaming_2.11/2.1.0-mdh2.1.0.1-SNAPSHOT/spark-streaming_2.11-2.1.0-mdh2.1.0.1-SNAPSHOT-tests.jar, seems unchanged`
**The reason is below:**
`[DEBUG]   (f) artifact = org.apache.spark:spark-streaming_2.11🫙2.1.0-mdh2.1.0.1-SNAPSHOT
[DEBUG]   (f) attachedArtifacts = [org.apache.spark:spark-streaming_2.11:test-jar:tests:2.1.0-mdh2.1.0.1-SNAPSHOT, org.apache.spark:spark-streaming_2.11🫙tests:2.1.0-mdh2.1.0.1-SNAPSHOT, org.apache.spark:spark

-mdh2.1.0.1-SNAPSHOT]`

when executing 'mvn deploy' to nexus during release.I will fail since release nexus can not be overrided.

## How was this patch tested?
Execute 'mvn clean install -Pyarn -Phadoop-2.6 -Phadoop-provided -DskipTests'

Spark SQL

This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.

Spark SQL is broken up into four subprojects:

  • Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
  • Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
  • Hive Support (sql/hive) - Includes an extension of SQLContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs.
  • HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.

Running sql/create-docs.sh generates SQL documentation for built-in functions under sql/site.
