> Key: HDFS-12834
> URL: https://issues.apache.org/jira/browse/HDFS-12834
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha
> Affects Versions: 2.7.3, 3.0.0-alpha4
> Reporter: Zbigniew Kostrzewa
> Assignee: Bharat Viswanadham
> Attachments: HDFS-12834.00.patch, HDFS-12834.01.patch

>
> On error {{DFSZKFailoverController}} exits with 0 return code which leads to
> problems when integrating it with scripts and monitoring tools, e.g. systemd,
> which when configured to restart the service only on failure does not restart
> ZKFC because it exited with 0.
> For example, in my case, systemd reported zkfc exited with success but in
> logs I have found this:
