Hi there-
Here are the recommendations from the HBase RefGuide:

... and they are consistently with what the book says (recommends 64-bit
OS and more memory).
Also, keep this in mind...

Hi All,
I have the Datanode, JobTracker and RegionServer daemons running on a
fleet of machines. Each of these machines have 8 G of memory and are
dedicated hardware for running HBase. How do you guys decided which %
of memory to assign to each ? What should this number be dependent on
?
Thank
You mean DataNode, _TaskTracker_ and RegionServer I assume.
DN and TT should not need more than 1G each - even that is excessive. You want
much of your resources free for actual work (map/reduce tasks if you are
running Hadoop MR).
I'll let HBase experts comment on RS.

Sorry, I meant *TaskTracker. The main purpose of the HBase cluster it
to run Map-Reduce jobs. The random read load is fairly low. Currently,
I have allocates 5 G to the Region Server, and 500 MB to Task Tracker
and 500 MB to DataNode.
