Tom White commented on WHIRR-525:
---------------------------------
I managed to reproduce this once, and looking at the logs it appears that the
region server failed to start:

The odd thing is that I can't issue an {{ruok}} to the ZK node from within the
cluster (it connects but returns nothing), whereas I get {{imok}} from outside.
This is a sporadic failure which seems to be 0.92 related, so I'm inclined to
commit this and have a follow up JIRA to fix it. What do you think? (Having
this in will help progress WHIRR-391 since there is overlap in some of the cdh
refactoring I'm doing there.)
