Subject [jira] Created: (HIVE-957) Partiition Metadata and Table Metadata
Date Mon, 30 Nov 2009 22:39:20 GMT
Partiition Metadata and Table Metadata
--------------------------------------

                 Key: HIVE-957
                 URL: https://issues.apache.org/jira/browse/HIVE-957
             Project: Hadoop Hive
          Issue Type: Bug
            Reporter: He Yongqiang


Right now, we choose to use partition lever metadata. All metadata (column names, column types,
fileformat, serde class, serde properties) right now are from partition level metadata. But
hive does not support a method now to alter all existing partitions' metadata, so users mostly
choose to alter table metadata, and think hive will use the new  table level metadata. 
One approach is that we may need to provide a way to let user alter all partitions' metadata
with one simple command. Right now a short term solution is to only get fileformat, serde
class metadata from paritition level metadata, and use all other metadata from table.

any comments?
