Description

Service is launched with TAR BALL artifacts. If a container is exited due to any reasons, container relaunch policy try to relaunch the container on same node with same container work space. As a result, container relaunch is keep on failing.

If container relaunch max-retry policy is disabled, then container never launched in any other nodes also rather it keep on retrying on same node manager which never succeeds.

Relaunching Container container_e05_1533635581781_0001_01_000002. Remaining retry attempts(after relaunch) : -4816.

There are two issues

1. Container relaunch is keep on failing
2. Log message is misleading
