Lars Hofhansl updated HBASE-4274: --------------------------------- Fix Version/s: (was: 0.94.0) 0.96.0 No movement, removing from 0.92. > RS should periodically ping its HLog pipeline even if no writes are arriving > ---------------------------------------------------------------------------- > > Key: HBASE-4274 > URL: https://issues.apache.org/jira/browse/HBASE-4274 > Project: HBase > Issue Type: Improvement > Components: regionserver, wal > Affects Versions: 0.92.0 > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Priority: Critical > Fix For: 0.96.0 > > > If you restart HDFS underneath HBase, when HBase isn't taking any write load, > the region servers won't "notice" that there's any problem until the next > time they take a write, at which point they will abort (because the pipeline > is gone from beneath them). It would be better if they wrote some garbage to > their HLog once every few seconds as a sort of keepalive, so they will > aggressively abort as soon as there's an issue. -- This message is automatically generated by JIRA.
