Re: Query regarding issue with zookeeper restart
I think it could be related to this:
https://issues.apache.org/jira/browse/ZOOKEEPER-1427
What do you think?

Would be great if you could submit a patch.

I believe the workaround you suggest will fix this - but I'd suggest
you remove both the accepted and current epoch files (not just one).
