Subject [jira] [Commented] (HIVE-9503) Update '*' descriptions
Date Thu, 29 Jan 2015 00:40:35 GMT


Xuefu Zhang commented on HIVE-9503:

I'm not sure of the difference between backup task and the "conditional task" that these two
properties are referring to, but I don't feel we need a property to control whether to have
a backup task. As long as we auto converted a join, we should have a backup task.

> '' flag does not apply to Spark or Tez, and only
to MR (which has the legacy conditional mapjoin)
> However, '' 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.
