 Key: HIVE-2368
 URL: https://issues.apache.org/jira/browse/HIVE-2368
 Project: Hive
  Issue Type: Bug
  Components: Metastore
Reporter: Sohan Jain
Assignee: Sohan Jain
 Fix For: 0.9.0

 Attachments: HIVE-2368.1.patch


 To determine if a column descriptor is unused, we call 
 listStorageDescriptorsWithCD(), which may return a big list of SDs.  This can 
 severely slow down dropping partitions.
 We can add a maximum number of SDs to return, and just ask for 1 SD, since we 
 are just doing an existential check.
