Description

In the following sequence, I expect the stats for partition 333 to be computed, but they are not:

1. In Impala: create table T (x int) paritioned by (y int)
2. In Impala: insert into table T partition (y=42) values (2)
3. In Hive: alter table T add partition (y=333)
4. In Impala: compute incremental stats T
5. In Impala: show table stats T
