Subject [jira] [Commented] (HIVE-12967) Change LlapServiceDriver to read a properties file instead of llap-daemon-site
Date Fri, 05 Feb 2016 09:19:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15133880#comment-15133880

Gopal V commented on HIVE-12967:
--------------------------------

The patch seems to be skipping some fairly important entries from the hive-site.xml 

{code}
2016-02-05T04:13:04,842 WARN  [main[]]: impl.LlapDaemon (LlapDaemon.java:main(336)) - Failed
to start LLAP Daemon with exception

{code}

{code}
+  public LlapDaemonConfiguration() {
+    super(false);
+    addResource(LLAP_DAEMON_SITE);
+  }
{code}

is not sufficient to pick up core-site.xml or yarn-site.xml shipped along-side.

> Having a copy of llap-daemon-site on the client node can be quite confusing, since LlapServiceDriver
generates the actual llap-daemon-site used by daemons.
> Instead of this - base settings can be picked up from a properties file.
> Also add java_home as a parameter to the script.
