Hadoop file system + HBase

Hi All,

What is the ideal set up for HDFS and HBase?

Do I install my HBase regionservers on the same machines that have HDFS datanodes?

Or, is it better to separate all of them? 


Thanks,
Harold

Thanks for the tip.

We usually run the namenode and the HBase master on the same machine.

Caveat, any machine that is not at least a dual core will have problems
running either Hadoop or HBase as both are very thread intensive.

Great. Thanks.

What about the HDFS NameNode and Hadoop Master? Do you separate them or put them on the same machine?

Run the regionserver beside the datanode; thats how most of us do it.  You
could separate them; there'd probably be little difference in performance
(but I haven't measured of late).
