Hi,

We are in the process of moving a small Hbase/Hadoop cluster from our
development to production environment.Our development environment were few
intel desktops (8 cores CPU/8 Gigs RAM/7200 rpm disks) running centOS while
the production environment are blades with (24 cores AMD CPU/32 gigs
RAM/15000 rpm disks) AMD architecture running centOS.

Strangely the hbase performance seems to degrade after moving stuffs to the
production enviroment (suppoesed to have more horse power).We are using the
latest and default installation for cloudera version of hadoop and hbase.No
changes to memory or other parameter were done on both the environment.

Any idea what could cause this.Could the AMD architecture be the
cause.Pointers to things to look for to improve performance in the
production cluster would be really appreciated.

Note: We ran "count" from hbase shell on a huge table and found the desktops
to be performing much better. We are in the process of comparing Map-Reduces
presently.
