Zoltan Haindrich commented on HIVE-20915:
-----------------------------------------

{quote}I will create a jira to update the test to use set hive.optimize.sort.dynamic.partition.threshold=-1,
is that OK Zoltan Haindrich ?{quote}

Sorry, but I don't think that would be a good idea...I might be misinterpreting your comments/point
of view. cc: [~jcamachorodriguez], [~ashutoshc]

> HIVE-20703 put dynamic sort partition optimization under cost based decision, but it
also makes the optimizer only available to tez. hive.optimize.sort.dynamic.partition works
with other execution engines for a long time, we should keep the optimizer available to them.
