> IF NOT EXISTS in INSERT OVERWRITE should not support dynamic partitions. However, we returns a wrong answer. 
> {noformat}
> CREATE TABLE table_with_partition(c1 string)
> PARTITIONED by (p1 string,p2 string)
> INSERT OVERWRITE TABLE table_with_partition
> partition (p1='a',p2='b')
> SELECT 'blarr2'
> INSERT OVERWRITE TABLE table_with_partition
> partition (p1='a',p2) IF NOT EXISTS
> SELECT 'blarr3'
> {noformat}
> {noformat}
> !== Correct Answer - 1 ==   == Spark Answer - 2 ==
>  [blarr2,a,b]               [blarr2,a,b]
> !                           [blarr3,a,blarr3]
> {noformat}
