Subject [jira] [Commented] (HIVE-6360) Hadoop 2.3 + Tez 0.3
Date Wed, 23 Apr 2014 07:30:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13977934#comment-13977934

Lefty Leverenz commented on HIVE-6360:
--------------------------------------

The Tez configuration parameters are documented in the wiki:  https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Tez.

The ORC configuration parameter (hive.exec.orc.zerocopy) still needs to be added to the wiki.

> There are some things pending that rely on hadoop 2.3 or tez 0.3. These are not released
yet, but will be soon. I'm proposing to collect these in the tez branch and do a merge back
once these components have been released at that version.
> The things depending on 0.3 or hadoop 2.3 are:
> - Zero Copy read for ORC
> - Unions in Tez
> - Tez on secure clusters
> - Changes to DagUtils to reflect tez 0.2 -> 0.3
> - Prewarm containers
