Lefty Leverenz commented on HIVE-16318:
---------------------------------------
Doc note: This adds *hive.llap.io.metadata.fraction* and changes the default
value of *hive.llap.io.allocator.alloc.min*, so they need to be documented in
the wiki for release 2.2.0.
* [Configuration Properties -- LLAP I/O |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAPI/O]
* [Configuration Properties -- LLAP I/O -- hive.llap.io.allocator.alloc.min |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.llap.io.allocator.alloc.min]
By the way, a prior change of default value for
*hive.llap.io.allocator.alloc.min* hasn't been documented yet -- see HIVE-13346.
Added a TODOC2.2.0 label.

> Labels: TODOC2.2.0

> We've run into HIVE-16233 and HIVE-15665 and given that 2.2 and 2.3 releases
> are approaching we are going to add workarounds for them, and then commit the
> above patches and revert the workarounds as soon as we can.
> Unfortunately this will result in cache wasting some memory on some datasets,
> but the alternatives, when they are encountered (usually only on large
> datasets), are worse.
