Chris Nauroth commented on HIVE-13008:
--------------------------------------
+1 (non-binding), pending pre-commit run. This is the right thing to do from
the perspective of integration with [HDFS
Federation|http://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-hdfs/Federation.html]
and use of
[ViewFs|http://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-hdfs/ViewFs.html]
as an abstraction over multiple file systems.
