Hi Michael,
I would be curious to know what advantage you are going to get by hashing a structured field. Has that structured field got very high selectivity so you end up with equally sized buckets (files) spread? How about the following hive> CREATE TABLE foo (id bigint, bar struct<a:string, b:string>) CLUSTERED BY (id) INTO 32 buckets; OK Time taken: 0.787 seconds HTH Mich Talebzadeh http://talebzadehmich.wordpress.com Author of the books "A Practitioners Guide to Upgrading to Sybase ASE 15", ISBN 978-0-9563693-0-7. co-author "Sybase Transact SQL Guidelines Best Practices", ISBN 978-0-9759693-0-4 Publications due shortly: Creating in-memory Data Grid for Trading Systems with Oracle TimesTen and Coherence Cache Oracle and Sybase, Concepts and Contrasts, ISBN: 978-0-9563693-1-4, volume one out shortly NOTE: The information in this email is proprietary and confidential.

Thanks a lot Michael
