Ted Yu updated HBASE-7382:
--------------------------
Release Note:
hbase.zookeeper.useMulti
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).

> HBASE-6775 adds support for ZK.multi ZKUtil and uses it for the 0.92/0.94
> compatibility fix implemented in HBASE-6710.
> ZK.multi support is most likely useful in 0.96, but since HBASE-6710 is not
> relevant for 0.96, perhaps we should find another use case first before we
> port.
