[jira] [Commented] (PIG-5305) Enable yarn-client mode execution of tests in Spark (1) mode

["Adam Szita (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-5305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16166543#comment-16166543 ] 

Adam Szita commented on PIG-5305:
---------------------------------

Attached [^PIG-5305.0.patch] to enable running tests in yarn-client mode for Spark execution.

Main changes:
* build.xml: added target to build a jar with all test classes. This is required so that we can pass this test jar onto SparkContext which then distributes it among Spark executors + set SPARK_MASTER env var to "yarn-client"
* SparkLauncher: added feature to re-initialize SparkContext when switching between cluster and local mode PigServers + only setting ChildFirstURLClassLoader during cluster mode

[~kellyzly] can you please take a look?
