Subject [jira] [Commented] (HBASE-9842) Backport HBASE-9593 and HBASE-8667 to 0.94

rajeshbabu commented on HBASE-9842:

Thanks Lars for fixing the test case.
The 0.94 patch at HBASE-9593 is hanging because we have only one regionserver which is getting
killed. But during master initialization we will retry infinitely until root region assigned.
Since there are no regionsevers its hanging there. In the current patch I have added one more
region server to open the -ROOT- and .META. regions. Even though started two regionservers
finally one will be online. without patch two will be online.

bq. Looks like is also wrong on the trunk patch.
In trunk patch starting 1 RS only. After the RS killed there wont be any regionserver still
master initialization not waiting for meta region to assign. I think the reason for that is
HBASE-9151(When meta server znode deleted and meta in FAILED_OPEN state, then hbck cannot
fix it. This scenario can come when all region servers stopped by stop command and didnt start
any RS within 10 secs(with default configurations).)
