Sergio Peña commented on HIVE-16024:
------------------------------------
As [~vihangk1] mentioned, seems this regression issue was introduced
unintentionally by HIVE-13788. [~hsubramaniyan] Do you know if HIVE-13788 was
attempting to prevent a user to use MSCK when hive.mapred.mode was in strict
mode? If we use strict mode, then users won't be allowed to recover unknown
partitions unless they mention the partition, but they're unknown.
> MSCK Repair Requires nonstrict hive.mapred.mode

> MSCK repair fails when hive.mapred.mode is set to strict
> HIVE-13788 modified the way we read up partitions for a table to improve
> performance. Unfortunately it is using PartitionPruner to load the partitions
> which in turn is checking hive.mapred.mode.
> The previous code did not check hive.mapred.mode.
