             Summary: Use the hive client method "getPartitionNames" to answer "SHOW PARTITIONS" queries on partitioned Hive tables
                 Key: SPARK-18572
                 URL: https://issues.apache.org/jira/browse/SPARK-18572
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Michael Allman


Currently Spark answers the {{SHOW PARTITIONS}} query by fetching all of the table's partition metadata from the external catalog and constructing partition names therefrom. The Hive client has a {{getPartitionNames}} method which is orders of magnitude faster, with the performance improvement scaling up with the number of partitions in the table. I believe we can use this method to great effect.

Further details are provided in the associated PR (coming shortly).
