> It is because StatsUtils uses the String.startWith to compare VARCHAR/DECIMAL 
> column type name with serdeConstants which are in lowercase.  But these type 
> names in stats might not be in lower case. We ran into a case where the type 
> name from TAB_COL_STATS/PART_COL_STATS was actually in uppercase (e.g. 
> VARCHAR, DECIMAL) because these column stats were populated from other HMS 
> clients like Impala.
> We need changes these type name comparison to be case insensitive
