-Re: Creating partition with __HIVE_DEFAULT_PARTITION__ value

If its any help I've done this kind of thing frequently:
1. create the table on the new cluster.
2. distcp the data right into the hdfs directory where the table resides on
the new cluster - no temp storage required.
3. run this hive command: msck repair table <table>; -- this command
will create your partitions for you - its pretty slick that way.
Let us know how it goes.
