Ted Yu updated HBASE-12957: --------------------------- Resolution: Fixed Hadoop Flags: Reviewed Status: Resolved (was: Patch Available) > region_mover#isSuccessfulScan may be extremely slow on region with lots of > expired data > --------------------------------------------------------------------------------------- > > Key: HBASE-12957 > URL: https://issues.apache.org/jira/browse/HBASE-12957 > Project: HBase > Issue Type: Improvement > Components: scripts > Reporter: hongyu bi > Assignee: hongyu bi > Priority: Minor > Fix For: 2.0.0, 1.1.0 > > Attachments: HBASE-12957-v0.patch > > > region_mover will call isSuccessfulScan when region has moved to make sure > it's healthy, however , if the moved region has lots of expired data > region_mover#isSuccessfulScan will take a long time to finish ,that may even > exceed "lease timeout".So I made isSuccessfulScan a get-like scan to achieve > faster response in that case. > workaround:before graceful_stop/rolling_restart ,call major_compact on the > table with small TTL -- This message was sent by Atlassian JIRA (v6.3.4#6332)
