Description

For deeply nested partitioned table, intermediate directories are not removed even if there is no partitions in it by removing them.

/deep_part/c=09/d=01
/deep_part/c=09/d=01/e=01
/deep_part/c=09/d=01/e=02
/deep_part/c=09/d=02
/deep_part/c=09/d=02/e=01
/deep_part/c=09/d=02/e=02

After removing partition (c='09'), directory remains like this,

/deep_part/c=09/d=01
/deep_part/c=09/d=02
