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. --------------------------- Thanks & Regards Himanish
