Subject [jira] [Commented] (HBASE-18502) Change MasterObserver to use TableDescriptor
Date Wed, 02 Aug 2017 14:42:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16111036#comment-16111036
] 

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.
