    Description

      This is a subtask of HIVE-5369. 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.
