Description

It seems that the HSClientProtocolPBClientImpl should implement Closeable as per the attached stack trace. The problem can be observed on a cluster running the latest branch-2.0.4-alpha with MAPREDUCE-5088 applied on top. The easiest way to reproduce it is to run an oozie pig job:

$ oozie job -oozie http://`hostname -f`:11000/oozie -run -DjobTracker=`hostname -f`:8032 -DnameNode=hdfs://`hostname -f`:17020 -DexamplesRoot=examples -config /tmp/examples/apps/pig/job.properties

Please also note that I can successfully submit simple jobs (Pi/Sleep) from a command line using hadoop jar command. Thus it seems related to MAPREDUCE-5088 change.
