I would suggest taking a look at my prior email again:
The client makes a connection to the server (tcp) but cannot
establish a session. This could be because you don't have a
functioning quorum, or perhaps maxClientCnxns is exceeded (does the
log mention "Too many connections from" anywhere?), etc... the server
logs will shed more light.
So far you've only included the client logs, as I mentioned it's clear
from the client log that the server is rejecting the session from the
client. Looking at the ZK servers logs for the time period in question
will shed more light.

If the master doesn't shut down, it means it's waiting on
something... you looked at the logs?
You say you ran ./jps ... did you install that in the local
directory? Also what do you mean "it didn't work as well"? What
didn't work? The command didn't return anything or the HMaster
process wasn't listed?
Also did you check the zookeeper logs like Patrick said? You
should see in there when the master tries to connect, and you
should see why it wasn't able to do so.
To help you I need more data about your problem.

Hi Daniel, I removed the property tags from the
hbase-site.xml.
Same error occurs.
Also one strange behaviour, If i give ./stop-hbase.sh , the
terminal
says
stopping master .................................... and never
stopped.
I couldnt able to ./jps to check the java in this scenario, it
didnt
work
aswell. So I killed the Hmaster start ( ps -ef | grep java)
Also manually need to kill Hregionserver both on master, slave1
and
slave2.
Any suggestions please.......

You set the tick time like this:

<value>1</value> <description>Property from ZooKeeper's
config zoo.cfg. The number of milliseconds of each tick.
See zookeeper.session.timeout description. </description>
1 means HBase has to report to zookeeper every 1 millisecond
and if for any reason it doesn't after 20ms, the session is
expired (!!). I recommend using the default value.
Also you should keep the same config on every node, rsync can
do
wonders.
