-------------------------------------
Summary: Deadlock with unknown lock holder in JVM in
java.security.Provider.getService()
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
Assignee: Tim Armstrong
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.

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.
