Ted Yu updated HBASE-4785: -------------------------- Status: Patch Available (was: Open) > Improve recovery time of HBase client when a region server dies. > ---------------------------------------------------------------- > > Key: HBASE-4785 > URL: https://issues.apache.org/jira/browse/HBASE-4785 > Project: HBase > Issue Type: Improvement > Reporter: Nicolas Spiegelberg > Assignee: Nicolas Spiegelberg > Priority: Minor > Fix For: 0.94.0 > > Attachments: HBASE-4785.patch, HBASE-4785.patch > > > When a region server dies, the HBase client waits until the RPC timesout > before learning that it needs to check META to find the new location of the > region. And it incurs this *timeout* cost for every region being served by > the dead region server. Remove this overhead by clearing the entries in cache > that have the dead region server as their values. -- This message is automatically generated by JIRA.
