[jira] [Commented] (AMBARI-19015) RegionServer Restart During Upgrade Fails Because of Missing Import When Formatting PID

["Jonathan Hurley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-19015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15705352#comment-15705352 ] 

Jonathan Hurley commented on AMBARI-19015:
------------------------------------------

Looks like a missing import based on the log from the agents:
{noformat}
Pid file {pid_dir}/hbase-{hbase_user}-regionserver.pid is empty or does not exist
{noformat}
