Subject Re: HBase failing to restart in single-user mode
Date Mon, 18 May 2015 08:14:49 GMT
Same for me, I had faced similar issues especially on my virtual machines
since I would restart them more often than my host machine.

Moving ZK from /tmp which could get cleared on reboots fixed the issue for
me.

Thanks,
Viral
