> It is very common that there are many repeated values in the result set of a query. 
As it currently stands, beeline does not attempt to cache any of these values and therefore
it consumes a lot of memory.
> Adding a string cache may save a lot of memory.  There are organizations that use beeline
to perform ETL processing of result sets into CSV.  This will better support those organizations.
