-----------------------------
The same issue on HDP2.6, any comments on how to workaround?

> Key: HDFS-8298
> URL: https://issues.apache.org/jira/browse/HDFS-8298
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: ha, namenode, qjm
> Affects Versions: 2.6.0, 2.7.3
> Environment: multiple clients, HDP 2.2, HDP 2.5, CDH etc
> Reporter: Hari Sekhon
> Priority: Major
>
> In an HDFS HA setup if there is a temporary problem with contacting journal
> nodes (eg. network interruption), the NameNode shuts down entirely, when it
> should instead go in to a standby mode so that it can stay online and retry
> to achieve quorum later.
> If both NameNodes shut themselves off like this then even after the temporary
> network outage is resolved, the entire cluster remains offline indefinitely
> until operator intervention, whereas it could have self-repaired after
> re-contacting the journalnodes and re-achieving quorum.
