Hi Ameet, That's the correct behaviour. In Hive, clustering and sorting happens within a partition. Inside each partition, there is only one value associated with the partition column therefore it would have no impact on clustering and sorting. Therefore, putting the partition column in clustered by/sorted by in the create table statement doesn't make sense.
Also, your create table statement should be something like (note the removal of col3 from the column list): create table abc ( col1 string, col2 string) partitioned by (col3 string) clustered by (col1) sorted by (col1) into 10 buckets; Mark Mark Grover, Business Intelligence Analyst OANDA Corporation www: oanda.com www: fxtrade.com ----- Original Message ----- From: "ameet chaubal" <ameetchau...@yahoo.com> To: user@hive.apache.org Sent: Thursday, May 10, 2012 2:24:02 PM Subject: partition column not allowed in clustered by clause ? Hi All, I am not able to create a table with partition column also included in the clustered by clause. create table abc ( col1, col2, col3 ) partitioned by (col3) clustered by (col1,col3) sorted by (col1,col3) into 10 buckets; fails with : FAILED: Error in semantic analysis: Invalid column reference Any reason why this is the case? Sincerely, Ameet
