Vivek Sharma created AMBARI-22864:
-------------------------------------
Summary: Agent commands hang even after freeing up disk space on
the host
Key: AMBARI-22864
URL: https://issues.apache.org/jira/browse/AMBARI-22864
Project: Ambari
Issue Type: Bug
Components: ambari-agent, ambari-server
Affects Versions: 2.6.2
Reporter: Vivek Sharma
Fix For: 2.6.2
*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.
