["Prasad Chakka (JIRA)" <ji...@apache.org>]

Prasad Chakka commented on HIVE-281:
------------------------------------

you mean in the ql.metadata interface or in the metastore db? the former is very easy but the later can be done when we refactor the schema for views etc.

> We should remove "isCompressed" option in the metastore. It's not used for anything now.
> The result of a query is compressed depending on the mapred.output.compress option instead of table property.
> Hadoop can automatically detect if the data is compressed or not, so we don't need this property in metastore.
