-----------------------------------
Summary: JobManager can't failover to hdfs with multiple namenodes
Key: FLINK-9960
URL: https://issues.apache.org/jira/browse/FLINK-9960
Project: Flink
Issue Type: Bug
Components: JobManager
Affects Versions: 1.4.0
Reporter: Julio Biason
When Hadoop/HDFS is running in HA mode, there may be more than one namenode
running: One active and another standby.
If, for whatever reasons, the server configured in high-availability.storageDir
is currently in standby mode (e.g., Hadoop failed over the other namenode), the
JobManager will refuse to start because it can't contact hdfs – in this case,
it should have a list of servers (up to 2) and, in case of a failure to
connect, go to the next one.
