[jira] [Created] (HIVE-5898) Make fetching of column statistics configurable

Prasanth J created HIVE-5898:

             Summary: Make fetching of column statistics configurable
                 Key: HIVE-5898
                 URL: https://issues.apache.org/jira/browse/HIVE-5898
             Project: Hive
          Issue Type: Sub-task
            Reporter: Prasanth J
            Assignee: Prasanth J


Current metastore api for fetching column statistics can only be done for per partition and per column basis. This will impact the performance of statistics annotation (during explain or explain extended) when the number of partitions and number of columns are large. Until metastore api is fixed, make fetching of column statistics configurable and set its default to false.
