Subject [jira] [Commented] (HIVE-6125) Tez: Refactoring changes
Date Sun, 10 Aug 2014 04:04:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14091993#comment-14091993

Lefty Leverenz commented on HIVE-6125:
--------------------------------------

This adds three hive.orc.* configuration parameters to HiveConf.java:  *hive.orc.splits.include.file.footer*,
*hive.orc.cache.stripe.details.size*, and *hive.orc.compute.splits.num.threads*.

Their descriptions are added in HIVE-6128 and they are documented in the wiki here:

* [Configuration Properties -- hive.orc.splits.include.file.footer |https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.orc.splits.include.file.footer]
* [Configuration Properties -- hive.orc.cache.stripe.details.size |https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.orc.cache.stripe.details.size]
* [Configuration Properties -- hive.orc.compute.splits.num.threads |https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.orc.compute.splits.num.threads]

> In order to facilitate merge back I've separated out all the changes that don't require
Tez. These changes introduce new interfaces, move code etc. In preparation of the Tez specific
classes. This should help show what changes have been made that affect the MR codepath as
well.
