Chia-Ping Tsai commented on HBASE-18502:
----------------------------------------
There are some deprecated methods introduced by HBASE-15575.
{code}
* @deprecated As of release 2.0.0, this will be removed in HBase 3.0.0
* (<a
href="https://issues.apache.org/jira/browse/HBASE-15575";>HBASE-15575</a>).
* Use {@link #preTruncateTableAction(ObserverContext, TableName)}.
{code}
Can we break the coprocessor API for 2.0? HBASE-17312 makes some incompatible
changes for MasterObserver but HBASE-13645 and HBASE-15575 don't.
> Change MasterObserver to use TableDescriptor
