[jira] [Created] (FLINK-8943) Jobs will not recover if DFS is
temporarily unavailable
Gary Yao created FLINK-8943:
-------------------------------
Summary: Jobs will not recover if DFS is temporarily unavailable
Key: FLINK-8943
URL: https://issues.apache.org/jira/browse/FLINK-8943
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.4.2, 1.5.0, 1.6.0
Reporter: Gary Yao
Fix For: 1.5.0, 1.6.0
*Description*
Job graphs will be recovered only once from the DFS. If the DFS is unavailable at the recovery attempt, the jobs will simply be not running until the master is restarted again.
*Steps to reproduce*
# Submit job on Flink Cluster with HDFS as HA storage dir.
# Trigger job recovery by killing the master
# Stop HDFS NameNode
# Enable HDFS NameNode after job recovery is over
# Verify that job is not running.
*Stacktrace*
