insert overwrite table fails with json serde

[GoogleCodeExporter]

Steps
1. Created an external table that points to the gzip log files
2. Select query with limit 10 or 100 returned results.
3. Now created a secondary external table that's pointing to a different 
location.
4. Used Insert Overwrite clause to pull out records from a certain day/month 
into a partition. 
5. the select statement succeeds but file creation fails

What is the expected output? What do you see instead?
a flat table in text file format. The job fails with following error .
