["Thejas M Nair (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-5794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13819419#comment-13819419 ] 

Thejas M Nair commented on HIVE-5794:
-------------------------------------

>  LOG.warn("Error starting HiveServer2 on attempt " + attempts, throwable);
It will be useful to indicate in the warning message that it will retry starting in x seconds.

> Thread.sleep(60L * 100L);
Did you mean 60L*1000L ?  ie, 60 seconds ?  

<description>This number of times HiveServer2 will attempt to start before exiting.</description>
Can you also mention the delay between retries here ? That will give an indication of how long the retries will be happening.
Did you mean the default waiting period to be 2.4 hours or 24 hours ?

> On startup the CLIService attempts to create scratch directories. If that fails, e.g. because the nn is also starting, HS2 fails to start. We should retry this operation this a few times with sleeps.
> It might be preferable todo this directly in HS2 main so that we can catch all errors.
