--------------------------------------
Summary: TSO panic in lease manager causes deadlock
Key: OMID-125
URL: https://issues.apache.org/jira/browse/OMID-125
Project: Apache Omid
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Philippe Laflamme
When the TSO loses its lease, it panics and invokes the panicker. The default
SystemExitPanicker calls System.exit synchronously which, in turn, calls the
shutdown hooks synchronously.
This causes the shutdown hooks to run within the Lease management scheduler's
lock which is also required to run shutdown.
To replicate the issue:
* start the tso server in HA
* from a ZK shell, update the tso-lease node:
** get /omid/tso-lease
** set /omid/tso-lease <the value from get>
* the tso server will panic but fail to shutdown properly
A patch is provided here https://github.com/apache/incubator-omid/pull/52
