Nick Dimiduk updated HBASE-27090:
---------------------------------
Attachment: shutdown-error.log
> Terminating standalone process is slow
> --------------------------------------
>
> Key: HBASE-27090
> URL: https://issues.apache.org/jira/browse/HBASE-27090
> Project: HBase
> Issue Type: Bug
> Components: Zookeeper
> Affects Versions: 3.0.0-alpha-2
> Reporter: Nick Dimiduk
> Priority: Major
> Attachments: shutdown-error.log
>
>
> Run hbase in standalone mode off of master, terminate the process with ^C.
> The process takes its sweet time to terminate. Luckily, we have some thread
> management utility code to inspect this behavior. Jetty takes a little time
> to shutdown, but does eventually. More problematic is the ZooKeeper client,
> which appears to not take a hint. In fact, the client attempts to initiate
> new connections to a service which has already been terminated, making
> matters worse.
