> 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.
