---------------------------------
Summary: 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
