Mohit Sabharwal commented on PIG-4489:
--------------------------------------
[~kellyzly], see https://issues.apache.org/jira/browse/SPARK-595
"local-cluster is only for unit tests, to emulate a distributed cluster in a
single JVM (it will still launch executors in separate ones, but at least you
won't need one JVM per slave)."
https://github.com/apache/spark/blob/a1fe59dae50f551d02dd18676308eca054ff6b07/core/src/test/scala/org/apache/spark/ShuffleSuite.scala#L50
{{SPARK_MASTER="spark://$MASTER_IP:$MASTER_PORT".}} doesn't make sense for unit
tests. It is for testing against a proper Spark cluster.

> Util.getLocalTestMode() currently only returns "tez_local" or "local".
> I see that ~212 testcases do this check, and we are not running these tests
> against Spark at this point.
> Currently all Spark tests run in local mode ("local" as a the Spark Cluster
> URL passed to JavaSparkContext), so we should enable these tests as well.
