Hi Jay,

  I think Gmail is cutting that off for you as it doesn't show duplicate
data.  Here you go:

#This is my /etc/hosts file ---
127.0.0.1   localhost  localhost.localdomain localhost4
localhost4.localdomain4
#::1         localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.122.200 hbase-master
192.168.122.201 hbase-regionserver1
192.168.122.202 hbase-regionserver2
192.168.122.203 hbase-regionserver3

It is what you should have for your host file.  I removed the pointer to
hbase-master from the 127 address, as that is not localhost.  Here is mine:

[root@cdh4-oozie-1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
10.20.217.122 cdh4-oozie-1.ent.cloudera.com cdh4-oozie-1
10.20.216.222 cdh4-oozie-2.ent.cloudera.com cdh4-oozie-2
10.20.216.237 cdh4-oozie-3.ent.cloudera.com cdh4-oozie-3
