> Hadoop HA checkpointer issue
> -----------------------------
>
> Key: HDFS-16289
> URL: https://issues.apache.org/jira/browse/HDFS-16289
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: dfs
> Affects Versions: 3.2.2
> Reporter: Boris Bondarenko
> Assignee: Uma Maheswara Rao G
> Priority: Minor
>
> In HA setup active namenode will reject fsimage sync from one of the two
> standby namenodes all the time. This maybe an edge case, in our environment
> it primarily affect standby cluster. What we experienced was memory problem
> on standby namenodes in the scenario when the standby node was not able to
> complete sync cycle for a long time.
> It is my understanding that the break out from the loop will only happen when
> doCheckpoint call succeeds otherwise it throws an exception and continues.
> I can provide more details on my findings with code references if necessary.
