Xuefu Zhang commented on HIVE-9503:
-----------------------------------
If hive.auto.convert.join.noconditionaltask.size is used by spark regardless of
hive.auto.convert.join.noconditionaltask, we should probably have a different
property. Reusing the same property while overwriting its meaning could cause
confusion for either existing users or new users.
> Update 'hive.auto.convert.join.noconditionaltask.*' descriptions

> Key: HIVE-9503
> URL: https://issues.apache.org/jira/browse/HIVE-9503
> Project: Hive
> Issue Type: Bug
> Components: Configuration
> Reporter: Szehon Ho
> Priority: Minor
>
> 'hive.auto.convert.join.noconditionaltask' flag does not apply to Spark or
> Tez, and only to MR (which has the legacy conditional mapjoin)
> However, 'hive.auto.convert.join.noconditionaltask.size' flag does apply to
> Spark, Tez, and MR, even though the description indicates it only applies if
> the above flag is on, which is true only for MR.
> These configs should be updated to reflect this case.
