Lefty Leverenz commented on HIVE-13934:
---------------------------------------
Doc note: This adds four configuration parameters to HiveConf.java, so they
will need to be documented in the wiki for release 2.1.1 (or 2.2.0 if that
comes first).
* *hive.tez.container.max.java.heap.fraction*
* *hive.tez.task.scale.memory.reserve-fraction.min*
* *hive.tez.task.scale.memory.reserve.fraction.max*
* *hive.tez.task.scale.memory.reserve.fraction*
* [Configuration Properties -- Tez |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Tez]
Added a TODOC2.1.1 label.
[~wzheng], please write a release note and explain the default value (-1) for
*hive.tez.task.scale.memory.reserve.fraction* since the parameter description
omits that information.
> Configure Tez to make nocondiional task size memory available for the
> Processor

> Currently, noconditionaltasksize is not validated against the container size,
> the reservations made in the container by Tez for Inputs / Outputs etc.
> Check this at compile time to see if enough memory is available, or set up
> the vertex to reserve additional memory for the Processor.
