> Fix possibility of deadlocking in refreshFileConnections when prefetch is

>
> 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
> Fix For: 3.0.0, 2.1.0, 1.5.0, 1.4.4, 2.0.1
>
> 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.
