Anoop Sam John commented on HBASE-20280: ---------------------------------------- The new fix of reopen channel making the possible dead lock right? The above exception u see with out even that fix (Reopen closed channel)? > Fix possibility of deadlocking in refreshFileConnections when prefetch is > enabled > --------------------------------------------------------------------------------- > > Key: HBASE-20280 > URL: https://issues.apache.org/jira/browse/HBASE-20280 > Project: HBase > Issue Type: Bug > Components: BucketCache > Affects Versions: 2.0.0-beta-2, 1.4.2 > Reporter: Zach York > Assignee: Zach York > Priority: Major > Attachments: HBASE-20280.master.001.patch > > > When prefetch on open is specified, there is a deadlocking case > where if the prefetch is cancelled, the PrefetchExecutor interrupts > the threads if necessary, when that happens in FileIOEngine, it > causes an ClosedByInterruptException which is a subclass of > ClosedChannelException. If we retry all ClosedChannelExceptions, > this will lock as this access is expected to be interrupted. > This change removes calling refreshFileConnections for > ClosedByInterruptExceptions. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
