> Many Hive performance issues are due to missing statistics. Either all, table
> or column statistics are missing. Potentially a new partition has been added
> and customer forgot to gather stats for that partition.
> A simple warning about a table or column missing statistics can be very
> helpful and makes hive more user friendly. Hive already has this information,
> its a matter of printing it out.
