Dima Spivak commented on HBASE-16842:

We started seeing this behavior in-house at Cloudera starting with CDH 5.7, 
when we rebased onto HBase 1.2, though I should note we sometimes saw it with 
the {{calm}} monkey, as well. This would suggest stability problems with the 
HBase master, though I haven't opened a separate JIRA as we didn't get any 
useful logging to go along with the isolated failures we saw.

> Running ITBLL with the slowDeterministic monkey I observe our primary and 
> backup masters in the test cluster can be both shut down by signals followed 
> by no attempt to start replacements for an extended period of time. Meanwhile 
> other actions continue to run that churn the regionserver fleet. Other 
> monkeys may enter a similar state, but I haven't observed it. The outcome of 
> the convergence of these behaviors is the eventual time out and termination 
> of the running integration test, which is obvious and expected and unhelpful, 
> so I believe unintentional.
