> Issue Summary:
> 1. When Namenode HA is enabled and "automatic failover" is selected, the
> "hdfs zkfc -formatZK" command is used to create a znode in ZooKeeper inside
> of which the automatic failover system stores its data.
> 2. When Namenode HA is enabled through the wizard, the user is asked to
> manually run this command.
> 3. When Namenode HA cluster is deployed using HA blueprint, the agent script
> has been executing "hdfs zkfc -formatZK -force -nonInteractive" to
> auto-format the znode. This means that everytime a ZKFC starts, we end up
> formatting the znode used to maintain the failover state.
> Fix:
> 1. Changing the command to "hdfs zkfc -formatZK -nonInteractive" so that the
> failover state is not reformatted and handling the case when the command
> returns a status=2 to indicate that the znode already exists and hence
> skipping formatting it.
