[jira] Created: (HIVE-281) Remove "iscompressed" parameter in the
metastore
Remove "iscompressed" parameter in the metastore
------------------------------------------------
Key: HIVE-281
URL: https://issues.apache.org/jira/browse/HIVE-281
Project: Hadoop Hive
Issue Type: Improvement
Affects Versions: 0.2.0, 0.3.0
Reporter: Zheng Shao
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.

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.
