I have a basic patch which prints table level column stats.. I can put up the patch for it today/tomorrow.. but for displaying partition level column stats we need to extend the “describe” statement to support column names.. https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-DescribePartition. If you see the DDL describe partition does not accept column names.
I can create JIRAs for the following tasks 1) Showing column stats in describe table 2) Showing column stats in describe partition If you would like to take up 2) please feel free to do so.
