As you can run the hadoop dfs commands from inside Hive, you can put both the commands in a script file and run the script file using hive. These are still two different commands but are together at one place and can be executed in the same environment in one go.

You can rename the LOCATION with an ALTER TABLE command. I don't believe there's a single, "atomic" statement to rename both the table and the directory.

My understanding is that renaming and external table doesn't rename the corresponding HDFS directory to match.  I would like to do this; I want to rename the table in Hive and also rename the HDFS directory so they match (they already match with the old name).  I'm not sure how to do this.  I'm worried that if I rename the HDFS directory through Hadoop, not Hive, that Hive will lose track of the directory, regardless of whether I rename the table in Hive as well.

I also don't want to drop and recreate the table because I don't want to notify Hive of all the partitions all over again.

Thoughts?
