> *STR*
> # Install a cluster with Ambari-2.6.2 and HDP-2.6.4.0
> # Go the host (say host1) running Nimbus component and restart Nimbus
> # Fill up the disk space on host1 (in my test, the disk space was filled up on the host
running Nimbus component)
> # Try to restart Nimbus. Nimbus restart expectedly fails with error:
> {code}
> Caught an exception while executing custom service command: <type 'exceptions.IOError'>:
[Errno 28] No space left on device; [Errno 28] No space left on device
> {code}
> # Now free up the disk space on host1 and try to restart Nimbus
>  
> *Result*
> Nimbus restart command hangs and eventually times out
> Looks like the issue is because the action queue is unable to create new command for
Nimbus restart.
