[jira] [Commented] (HIVE-15956) StackOverflowError when drop lots
of partitions
[ https://issues.apache.org/jira/browse/HIVE-15956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16409383#comment-16409383 ]
Ganesha Shreedhara commented on HIVE-15956:
-------------------------------------------
I tested that this patch works fine by dropping the partitions in batches. This will help when there are thousands of partitions to drop. I tested dropping ~40k partitions in the batches of 500.
It would be great if someone can review this patch.

> 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:
