Your HBase team are pleased to announce the release of HBase 0.92.1.
Download it from your favorite Apache mirror [1].  It should also be available
up in maven.

HBase 0.92.1 is a bug fix release.  For a complete list of changes, see the
release notes [2].

If upgrading from 0.90.x to 0.92.1, see the upgrade guide [3].  We recommend
you study it closely before you move to this release.

Yours,

P.S. Thanks goes out to all who contributed to this release!

Jonathan H filed HBASE-5603: rolling-restart.sh script hangs when
attempting to detect expiration of /hbase/master znode
0.92.0 was affected by the above JIRA.

I wonder if rolling-restart was tested for 0.92.1

FYI 0.92 builds against 3.4.3 and ZOOKEEPER-1059 was integrated to 3.4.0

If rolling restart was important, it would have been tested is my
guess.  But it would seem that it is a script that is not used and
that has since rotted in bin.  This is a little understandable given
it was a coarse restart of all regionservers w/o regard to region
placement and thus was superceded in 0.90 by bin/graceful_restart.sh.
See the manual for a prescription for rolling restart based on
graceful_restart.sh that has been used extensively at my place of
employ.

Thanks for the update.

I only found bin/graceful_stop.sh in both 0.90 and trunk.

--graceful option has recently been added to bin/rolling-restart.sh
I think the above new option does address region placement issues.

Cheers
