-----------------------------------
Hey Vinay. Thanks a lot for doing this - it's been on my list but hadn't gotten
to it yet. Do you plan to add a test case, perhaps against the BKJM
implementation?
I'll look at the code as soon as I can.
> Namenode INITIALIZESHAREDEDITS should be able to initialize all shared

> Currently, NameNode INITIALIZESHAREDEDITS provides ability to copy the edits
> files to file schema based shared storages when moving cluster from Non-HA
> environment to HA enabled environment.
> This Jira focuses on the following
> * Generalizing the logic of copying the edits to new shared storage so that
> any schema based shared storage can initialized for HA cluster.
> * Ability to Initialize new shared storage from existing shared storage when
> moving from One shared storage to another shared storage (Might be because of
> cost, performance, etc. For ex: Moving from NFS to BKJM/QJM).
