It is only a warning However, you should consider using hdfs dfs as opposed to hadoop fs I guess someone realised that “hadoop” is the name of eco system (HDFS + MapReduce) and hdfs is the actual file J which is more appropriate for a command syntax Mich Talebzadeh http://talebzadehmich.wordpress.com Author of the books "A Practitioner’s Guide to Upgrading to Sybase ASE 15", ISBN 978-0-9563693-0-7. co-author "Sybase Transact SQL Guidelines Best Practices", ISBN 978-0-9759693-0-4Publications due shortly:Creating in-memory Data Grid for Trading Systems with Oracle TimesTen and Coherence CacheOracle 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.

Just want to know does it make sense? Is there any concern about the functionality? Regards, Mahmood
