Subject [jira] [Commented] (HIVE-12623) Add an option to force allocation of fragments on requested nodes
Date Wed, 23 Dec 2015 08:01:46 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15069363#comment-15069363

Lefty Leverenz commented on HIVE-12623:
---------------------------------------

Doc note:  This adds *hive.llap.task.scheduler.locality.delay* to HiveConf.java so it needs
to be documented in the wiki for 2.0.0 (in a new section for LLAP parameters, to be created
for HIVE-9850 and HIVE-11908).

* [Hive Configuration Properties | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-HiveConfigurationProperties]

> Currently, fragments are sent to random nodes if the requested node does not have capacity.
In certain situations there's more to be gained by sending the fragments to the requested
node only.
