Nandor Kollar commented on PIG-5157:
------------------------------------
[~kellyzly] I'll have look at it. It seems that there's an other issue noticed
while trying to execute a simple script (not from unit test), Pig hangs. The
problem is with synchronized methods in JobMetricsListener and SparkListener:
since these are now two different objects, synchronized will lock on different
object, and wait/notify is also called on different instances. I'll update the
patch so that every method in JobMetricsListener synchronizes on the its
sparkListener private field, and calls wait() on this instance.
> Upgrade to Spark 2.0
