Lars Hofhansl commented on HBASE-7502:
--------------------------------------
test3686a also fails occasionally in 0.94 and trunk. I just increased the
scanning timeout to 15000 (from 10000)... But the race you mention might have
been the cause there too.

> TestScannerTimeout#test3686a fails consistently on snapshot branch. This is
> because there is an increase in the number of watches on the rs znode and its
> deletion takes more time now. The repercussion is that when test3686a starts,
> it ensures that there are two regionservers and it counts the aborted
> regionserver as a live one. While processing, it kills one of its server, and
> also the znode of the previously aborted server expires. Overall effect is
> there are no regionservers now, and client hangs.
