Duo Zhang updated HBASE-24506:
------------------------------
Priority: Critical (was: Major)
> async client deadlock
> ---------------------
>
> Key: HBASE-24506
> URL: https://issues.apache.org/jira/browse/HBASE-24506
> Project: HBase
> Issue Type: Bug
> Components: asyncclient
> Affects Versions: 2.2.4
> Reporter: Whitney Jackson
> Priority: Critical
>
> I ran into an issue where one instance in a cluster of application servers
> backed by HBase stopped processing requests. Looking at a thread dump, it
> seems HBase client threads are deadlocked:
> https://pastebin.com/raw/B3FJL1Ag
> The deadlock seemed to happen at the same time that a region server was
> abruptly stopped (the physical server was restarted unexpectedly).
> I'm using the hbase async API. The hbase client version is 2.2.4. The server
> is running 2.2.4 as well.
