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
> LLAP - allow using elevator without cache

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