> Ambari detects hive processes by pid, not reliable method
> ---------------------------------------------------------
>
> Key: AMBARI-8890
> URL: https://issues.apache.org/jira/browse/AMBARI-8890
> Project: Ambari
> Issue Type: Bug
> Reporter: Andrew Onischuk
> Assignee: Andrew Onischuk
> Fix For: 2.0.0
>
>
> PROBLEM:
> Ambari 1.6.1 detects whether processes are running by the presence of pid
> files. This may not be a problem for datanodes and nodemanagers, but it is a
> problem for hive metastore and hiveserver2. If there are hive metastore and
> hive server2 processes running, but pid files are missing, Ambari will start
> another instance. The end result is that hive services will not function.
> There have been quite some customers encountered this problem. Ambari should
> not rely on pid file.
