------------------------------------------
Summary: Reimplement HCatClientHMSImpl.dropPartitions() with
HMSC.dropPartitions()
Key: HIVE-9588
URL: https://issues.apache.org/jira/browse/HIVE-9588
Project: Hive
Issue Type: Bug
Components: HCatalog, Metastore, Thrift API
Affects Versions: 0.14.0
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
{{HCatClientHMSImpl.dropPartitions()}} currently has an embarrassingly
inefficient implementation. The partial partition-spec is converted into a
filter-string. The partitions are fetched from the server, and then dropped one
by one.
Here's a reimplementation that uses the {{ExprNode}}-based
{{HiveMetaStoreClient.dropPartitions()}}. It cuts out the excessive
back-and-forth between the HMS and the client-side. It also reduces the memory
footprint (from loading all the partitions that are to be dropped).
