[jira] [Commented] (HIVE-10012) LLAP: Hive sessions run before Slider registers to YARN registry fail to launch

["Siddharth Seth (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-10012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14490497#comment-14490497 ] 

Siddharth Seth commented on HIVE-10012:
---------------------------------------

Glanced over. Mostly looks good to me. This removes some of the log messages when a host is selected for locality, which may be useful for debugging.
Also there's a check for local addresses which needs to be added back to the FixedRegistryImpl.
{code}
inetAddress = InetAddress.getByName(host);
          if (NetUtils.isLocalAddress(inetAddress)) {
{code}
Required to match the hostname reported by a daemon and the one used by the scheduler.

> The LLAP YARN registry only registers entries after at least one daemon is up.
> Any Tez session starting before that will end up with an error listing zookeeper directories.
