-------------------------------

Hi Daniel, sorry, patch 1 breaks some core set UT (launched by "ant 
-Djavac.args="-Xlint -Xmaxwarns 1000" clean test-commit -Dhadoopversion=23")
The error is like
{code}
2016-08-23 21:31:37,226 [JobControl] ERROR 
org.apache.pig.backend.hadoop23.PigJobControl  - Error while trying to run jobs.
java.lang.IllegalStateException: Job in state DEFINE instead of RUNNING

{code}

I will study it tomorrow. Sorry for the inconvenience.
