How does that sound? At a later point in a different JIRA we can work on a more general initialization
system which is totally agnostic to the type of journal manager.

Sounds good to me. +1

Here is the JIRA to support shared edits dirs(other than file based). HDFS-3287

@Amith, you can go ahead with this change as a limitation of non-file based shared dirs.

> # 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.

edits dir's contents have been replaced without any prompting.
