Yu Li updated HBASE-15711:
--------------------------
Release Note: In HBASE-15711 a new client side property
hbase.client.log.batcherrors.details is introduced to allow logging full
stacktrace of exceptions for batch error. It's disabled by default and set the
property to true will enable it.
Add some document in release note.
