Subject Re: Error inserting data to ORC table
Date Wed, 27 Nov 2013 19:01:37 GMT
Hi Juan

This seems like a bug in version 2 of RLE (Run Length Encoding) that was implemented in Hive
0.12. New version of RLE can be disabled by setting hive.exec.orc.write.format=“0.11”.
This will fallback to old version RLE. 

The reason why changing it to string type works is that, string columns uses adaptive dictionary
encoding to encode the column whereas integers uses run length encoding.

Can you file a bug for this with possible steps for reproducing this issue? Also what dataset
are you using? Will it be possible to post the segment of the dataset that causes this failure
along with the bug?

When I change the column type to STRING the insert works fine.
