Subject Re: [VOTE] Sixth release candidate for HBase 1.0.0 (RC5) is available. Please vote by Feb 19 2015
Date Fri, 20 Feb 2015 08:38:27 GMT
Thanks for tests and votes so far.

Here is my official +1 (see above for my tests).

I was inspecting a similar issue today in the cluster with
IntegrationTestLoadAndVerify with destructive CM, and the log splitting did
not finish in 3 attempts. I think the issue is a not that critical though,
I think it is due to a race between timeout monitor and some slowness in
task heartbeat due to a loaded master (will open a jira if I nail down the
exact reason).

We need at least one more vote. I'll extend the voting for this RC (RC5)
until 20th midnight PST. Please let me know if you intend to spend some
more time on testing. We can extend the deadline.

Cheers,
Enis
