Zoltan Haindrich commented on HIVE-15956:
-----------------------------------------
[~niklaus.xiao] sorry for the late response...yes I've tried it with 100 ; and
it still produced the same issue, I'll take a look again; and peek into it
whenever this could be covered with a unit test or not....my test runs >10
minutes....
I've peeked into if a unit test can be created for this case...but it seems to
me that {{dropPartitions}} is currently not covered (or I'm looking at the
wrong files :)
> StackOverflowError when drop lots of partitions

> Repro steps:
> 1. Create partitioned table and add 10000 partitions
> {code}
> create table test_partition(id int) partitioned by (dt int);
> alter table test_partition add partition(dt=1);
> alter table test_partition add partition(dt=3);
> alter table test_partition add partition(dt=4);
> ...
> alter table test_partition add partition(dt=10000);
> {code}
> 2. Drop 9000 partitions:
> {code}
> alter table test_partition drop partition(dt<9000);
> {code}
> Step 2 will fail with StackOverflowError:
> {code}
