Subject [jira] [Commented] (HIVE-12597) LLAP - allow using elevator without cache
Date Thu, 07 Jan 2016 02:07:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15086667#comment-15086667
] 

Lefty Leverenz commented on HIVE-12597:
---------------------------------------

Doc note:  This adds six LLAP configuration parameters to HiveConf.java in release 2.0.0,
so they need to be documented in a new LLAP section of Configuration Properties (along with
those listed in a comment on HIVE-11908).

* hive.llap.io.memory.mode
* hive.llap.io.allocator.alloc.min
* hive.llap.io.allocator.alloc.max
* hive.llap.io.allocator.arena.count
* hive.llap.io.memory.size
* hive.llap.io.allocator.direct

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

This also _removes_ six configuration parameters that were added to 2.0.0 by HIVE-11908 and
haven't been documented yet, so no doc changes are needed for them -- just make sure they
don't get documented:

* hive.llap.io.use.lowlevel.cache
* hive.llap.io.cache.orc.alloc.min
* hive.llap.io.cache.orc.alloc.max
* hive.llap.io.cache.orc.arena.count
* hive.llap.io.cache.orc.size
* hive.llap.io.cache.direct

> Elevator is currently tied up with cache due to the way the memory is allocated. We should
allow using elevator with the cache disabled.
