Summary: Sometimes daemons keep running even after "kill -9" from
daemon-stop script
Key: HADOOP-15527
URL: https://issues.apache.org/jira/browse/HADOOP-15527
Project: Hadoop Common
Issue Type: Bug
Reporter: Vinod Kumar Vavilapalli
Assignee: Vinod Kumar Vavilapalli
I'm seeing that sometimes daemons keep running for a little while even after
"kill -9" from daemon-stop scripts.
Debugging more, I see several instances of "ERROR: Unable to kill ${pid}".
Saw this specifically with ResourceManager & NodeManager - {{yarn --daemon
stop nodemanager}}. Though it is possible that other daemons may run into this
too.
Saw this on both Centos as well as Ubuntu.
