specify partition metadata at insertion time
--------------------------------------------
Key: HIVE-1436
URL: https://issues.apache.org/jira/browse/HIVE-1436
Project: Hadoop Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Namit Jain
Assignee: He Yongqiang
Fix For: 0.7.0
Currently, the partition metadata is inferred from the table being inserted
into.
So, it is not possible to convert a old partition to RCfile unless the table is
first converted to RCFile, and the older
partition then inserted into.
But, for some reason, if the table cannot be converted to RCFile (say a old
process is loading data into that table),
there is no way to convert the older partition from sequence file to rcfile.
There should be a way to do so, something like:
insert overwrite table T partition (..)
select......
stored as RCFile;
