Zheng Shao commented on HIVE-1468:
----------------------------------
"select queries" means "SELECT" without "INSERT", correct?
I agree that we should treat these queries differently, specifically, no
compression (or maybe use lzo to same bandwidth - clients can be in other data
centers) will be a big win.
> intermediate data produced for select queries ignores
> hive.exec.compress.intermediate

> > explain extended select xxx from yyy;
> ...
> File Output Operator
> compressed: true
> GlobalTableId: 0
> looks like we only intermediate locations identified during splitting mr
> tasks follow this directive. this should be fixed because this forces clients
> to always decompress output data (even if the config setting is altered).
