> Key: IMPALA-7482
> URL: https://issues.apache.org/jira/browse/IMPALA-7482
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.0
> Reporter: Tim Armstrong
> Priority: Critical
> Labels: hang
> Attachments: vb1220-jstack2.out
>
>
> We've seen several instances of these mystery deadlocks in impalad's embedded JVM. The signature is a deadlock stemming from sun.security.provider.Sun being locked by an unknown owner.
> {noformat}
> Found one Java-level deadlock:
> =============================
> "Thread-24":
> waiting to lock monitor 0x0000000012364688 (object 0x000000008027ef30, a sun.security.provider.Sun),
> which is held by UNKNOWN_owner_addr=0x0000000014120800
> {noformat}
> If this happens in HDFS, it causes HDFS I/O to hang and queries to get stuck. If it happens in the Kudu client it also causes hangs.
