Subject [jira] [Commented] (HIVE-15827) LLAP: status tool breaks out of watch mode when live instances is 0
Date Tue, 07 Feb 2017 00:31:41 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15855047#comment-15855047

Prasanth Jayachandran commented on HIVE-15827:
----------------------------------------------

[~sershe] makes sense. But I am not sure if container start = application start. I was under
that assumption. 
I think your patch will still be required. PathChildrenCache ctor can throw exception (ensurepath
check) which is not within try..catch block.. and there are many places where getInstances()'s
IOException is not caught. Will review your patch :)
