Review request for Ambari, Attila Magyar, Dmitro Lisnichenko, Robert Levas, and
Sebastian Toader.
Bugs: AMBARI-20632
https://issues.apache.org/jira/browse/AMBARI-20632
Repository: ambari
Description
-------
Pattern
```
while not queue.empty():
queue.get(False)
```
does not work well, because .empty() call often returns True while there are
still some items in queue. Added checking queue size(.qsize()) and some guards
not to block too long in read function if queue is really empty but .empty()
and .qsize() returning false information.
Diffs
-----
ambari-agent/src/main/python/ambari_agent/StatusCommandsExecutor.py 04a3e85

Testing
-------
mvn clean test, manual tests to check if queues really drained fast enough.
Thanks,
Eugene Chekanskiy
