> {color:#172b4d}Creating a partition with data and adding another partition is leading to unbalanced calls to open/commit transaction during get_partitions_by_names call.{color}
> {color:#172b4d}Issue was discovered during REPL DUMP operation which uses  this HMS call to get the metadata of partition. This error occurs when there is a partition with no column statistics.{color}
> {color:#172b4d}To reproduce:{color}
> {code:java}
> CREATE TABLE student_part_acid(name string, age int, gpa double) PARTITIONED BY (ds string) STORED AS orc;
> LOAD DATA INPATH ‘/user/hive/partDir/student_part_acid/ds=20110924’ INTO TABLE student_part_acid partition(ds=20110924);
> ALTER TABLE student_part_acid ADD PARTITION (ds=20110925);
> Now if we try to preform REPL DUMP it fails with this the error "Unbalanced calls to open/commit transaction" on the HS2 side.
