-------------------------------------------
I think this is same as HDFS-3862 right?
> Add config to ZKFC to disable fencing
> -------------------------------------

> Key: HDFS-4915
> URL: https://issues.apache.org/jira/browse/HDFS-4915
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha
> Affects Versions: 3.0.0
> Reporter: Todd Lipcon
>
> With QuorumJournalManager, it's not important for the ZKFCs to perform any
> fencing. We currently workaround this by setting the fencer to /bin/true, but
> the ZKFC still does things like create "breadcrumb znodes", etc. It would be
> simpler to add a config to disable fencing, and then the ZKFC's job would be
> simpler
