Subject [jira] [Commented] (YARN-2980) Move health check script related functionality to hadoop-common
Date Tue, 07 Apr 2015 23:33:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14484334#comment-14484334
] 

Junping Du commented on YARN-2980:
----------------------------------

What does "Abey khali" means?
{code}
+    if(!NodeHealthScriptRunner.shouldRun(nodeHealthScript)) {
+      LOG.info("Abey khali");
+      return null;
+    }
{code}
If meaningless, I will reopen this JIRA until we have a fix.

> HDFS might want to leverage health check functionality available in YARN in both namenode
https://issues.apache.org/jira/browse/HDFS-7400 and datanode https://issues.apache.org/jira/browse/HDFS-7441.
> We can move health check functionality including the protocol between hadoop daemons
and health check script to hadoop-common. That will simplify the development and maintenance
for both hadoop source code and health check script.
> Thoughts?
