Description

While testing Flink 1.3.0 RC1, I ran into the following issue on the JobManager.

2017-05-19 14:41:38,030 INFO  org.apache.flink.runtime.webmonitor.JobManagerRetriever       - New leader reachable under akka.tcp://flink@permanent-qa-cluster-i7c9.c.astral-sorter-757.internal:36528/user/jobmanager:6539dc04-d7fe-4f85-a0b6-09bfb0de8a58.

The problem is the following:

JobManager1 starts from a yarn-session.sh
Job1 gets submitted to JobManager1
JobManager1 dies
YARN starts a new JM: JobManager2
in the meantime, errors on the yarn-session.sh appear, shutting down the session. This includes deleting the yarn staging directory in HDFS.
JobManager2 is unable to start a new Taskmanager because files in staging got deleted by the client.
