BKJM - anyone using it?
Hey folks,
Is anyone using BKJM? The BookKeeper-based HA approach was developed around
the same time as QuorumJournalManager, but I haven't seen much reported
about it in the last year, and I'm not aware of anyone having deployed BKJM
in any production use cases.
If no one is using it, I would propose removing it from the HDFS tree - if
anyone would like to experiment with it in the future, it could be
built/developed on github as an external project. If a significant
community emerges in the future, we could consider moving it back in.
(this isn't a formal vote thread, just trying to find out if it is indeed
abandoned)
-Todd

One small correction to my previous mail thread, Bookkeeper latest version in 4.2.2 and planning to upgrade to this version.
Thanks,
Rakesh

Hi Todd,
We have been extensively using the Bookkeeper based HA approach from the beginning. Also, we have many internal and external customers which we have already deployed and started using the BKJM based shared memory features.
Recently Bookkeeper has released 4.2.0 version, we have plans to upgrade Bookkeeper to this version. As Uma mentioned, we are trying to work on the pending activities of HDFS-3399 JIRA.
Regards,
Rakesh
