Hi,
I have streaming job ( Flink 1.5.5 ) which was running on Hadoop hortonworks
cluster with 150 parallelism (25 * 6). It has checkpoint enabled .
One of the host in Hadoop went down which caused job to restart container
and restart from last checkpoint.
But it could not restart due to following exception . It went to loop to
recover from state .
