You could also specify fully qualified hdfs path in the create table command. It could look like
create external table test(key string ) row format delimited fields terminated by '\000' collection items terminated by ' ' location 'hdfs://new_master_host:port/table_path'; Then you can use the 'insert overwrite' command to move all data to the new table. You can use dynamic partitioning to move partitioned tables. Please use the following options: SET hive.exec.dynamic.partition=true; SET hive.exec.dynamic.partition.mode=nonstrict; That way you will have the data copied and all the partitions created correctly for you.

I distcp all data to new cluster, and then copied the metadata directory to new cluster. hive comes up fine and show tables etc but the hive location is still pointing to old cluster There is one command alter table table_name set location new_location but it doesnt work for partitioned tables, is there a way we can do it for *ALL* partitions easily ?? Best Bhupesh
