Review request for Ambari, Aravindan Vijayan, Dmytro Sen, and Sid Wagle.
Bugs: AMBARI-19953
https://issues.apache.org/jira/browse/AMBARI-19953
Repository: ambari
Description
-------
After switching AMS to embedded mode, AMS HBase region server process from
previous AMS configs is still alive.
Steps to reproduce:
1. install a cluster with AMS distributed mode
2. ps -elf | grep ams
3. switch AMS to embedded mode
4. restart AMS
5. ps -elf | grep ams and will see AMS HBase regionserver process from previous
AMS distributed configs is still alive
The fix is when AMS is in embedded mode, make sure no residual region server
process is running at collector stop.
