Rohini Palaniswamy commented on TEZ-1231:
-----------------------------------------
Would prefer keeping io.sort.mb but defaulting to some fraction like Xmx if not
specified. Refer MAPREDUCE-5785 as well. Would be good if both MR and Tez had
same behavior. Will be easy for user to switch.

> Key: TEZ-1231
> URL: https://issues.apache.org/jira/browse/TEZ-1231
> Project: Apache Tez
> Issue Type: Improvement
> Reporter: Siddharth Seth
> Priority: Blocker
>
> Separate configs used by runtime Inputs/Outputs and framework specific
> configs As an example - task memory configs are not related to any Input /
> Output. Similarly for Credentials.
> Other possible config changes
> - Rename TEZ_RUNTIME_INPUT_BUFFER_PERCENT, which is a fairly confusing name
> - Get rid of the separation between INPUT/OUTPU in config names (e.g.
> INPUT_KEY, OUTPUT_KEY replaced with just KEY)
> - Move TEZ_RUNTIME_INTERMEDIATE_INPUT_KEY_SECONDARY_COMPARATOR_CLASS to
> MapReduce
