stack commented on HBASE-7847:
------------------------------
This patch seems unrelated to:
{code}
<property>
<name>hbase.zookeeper.useMulti</name>
<value>false</value>
<description>Instructs HBase to make use of ZooKeeper's multi-update
functionality.
This allows certain ZooKeeper operations to complete more quickly and
prevents some issues
with rare Replication failure scenarios (see the release note of HBASE-2611
for an example).
IMPORTANT: only set this to true if all ZooKeeper servers in the cluster
are on version 3.4+
and will not be downgraded. ZooKeeper versions before 3.4 do not support
multi-update and
will not fail gracefully if multi-update is invoked (see
ZOOKEEPER-1495).</description>
</property>
{code}
It should be related?
