Swarnim Kulkarni commented on HIVE-7116:
----------------------------------------
+1 for shims. Very clean approach.
Should we have some tests to prove that this actually fixes the permissions
issue? Also adding a new method to HadoopShims seems like would make it
non-passive. Not sure how much we care about passivity in shims but just a
thought. Since it is an interface, not sure if we can even do much about it
anyways. :)
Much thanks for looking into this Vikram!

> We change permissions of the directory creation to 777 for HiveServer 2
> operation and it turns out that because of HDFS caching, it does not reflect
> once created. We need to use the non-cached version of the API to get a
> FileSystem object to fix this.
