Thejas M Nair commented on HIVE-6152:
-------------------------------------
I think it will be better to use same code path with and without viewfs. That
change should work for non viewfs case as well. That way we don't have another
untested combination.
> insert query fails on hdfs federation + viewfs

> This is because Hive first writes data to /tmp/ and than moves from /tmp to
> final destination. In federated HDFS recommendation is to mount /tmp on a
> separate nameservice, which is usually different than /user. Since renames
> across different mount points are not supported, this fails.
