> To reproduce:
> # Configure a NameNode with namedirs and a shared edits dir, all of which are empty.
> # Run hdfs namenode -format. Namedirs and shared edits dir gets populated.
> # Delete the contents of the namedirs. Leave the shared edits dir as is. Check the timestamps
of the shared edits dir contents.
> # Run format again. The namedirs as well as the shared edits dir get formatted. The shared
edits dir's contents have been replaced without any prompting.
