Description

Use to do this in the logs:

java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b25)
Java HotSpot(TM) Server VM (build 11.0-b12, mixed mode)
ulimit -n 16384

Change it to...

ulimit -n 256
2008-12-11 10:36:19,209 INFO org.apache.hadoop.hbase.master.HMaster: vmName=Java HotSpot(TM) 64-Bit Server VM, vmVendor=Sun Microsystems Inc., vmVersion=1.6.0_03-p3-landonf_19_aug_2008_15_52-b00
2008-12-11 10:36:19,209 INFO org.apache.hadoop.hbase.master.HMaster: vmInputArguments=[-Xmx1000m, -XX:+HeapDumpOnOutOfMemoryError, -Dhbase.log.dir=/Users/stack/Documents/checkouts/hbase/trunk/bin/../logs, -Dhbase.log.file=hbase-stack-master-durruti.desk.hq.powerset.com.log, -Dhbase.home.dir=/Users/stack/Documents/checkouts/hbase/trunk/bin/.., -Dhbase.id.str=stack, -Dhbase.root.logger=INFO,DRFA, -Djava.library.path=/Users/stack/Documents/checkouts/hbase/trunk/bin/../lib/native/Darwin-amd64-64]

Adds args and more stats on vm (whether 32bit or 64bit, heap size, etc).
