             Summary: Sanity check for in-memory compaction policy
                 Key: HBASE-22529
                 URL: https://issues.apache.org/jira/browse/HBASE-22529
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.1.4
            Reporter: Junegunn Choi


Currently, if a column family is altered with an invalid in-memory compaction policy via {{Admin}} API, the regions for the table get stuck indefinitely.

This patch adds a sanity check for the value so that such alter operation should not proceed.
