What does the "hostname" command return on the master?
Do you have any backup-masters configured?
What is the contents of your regionservers file?

Does the IP you listed properly handle DNS resolution? You should make
sure
forward and reverse look up work properly for hosts used.
Generally you should also configure things via host name and not IP
address.

Hi,
You should not do this, as localhost should resolve to the own host.
This
is probably some missing property on the clients hbase configuration
(make
sure you have a proper hbase-site.xml on client's classpath or set
configuration programatically). As a start, check if you had set the
properties below on your client's hbase config.
<property>
<name>hbase.zookeeper.quorum</name>
<value>ZK_HOSTS</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>

Hello guys
I am using the hbase java api to connect to hbase remotely, but when I
executed the java code, got |MasterNotRunningException|. When I
debugged
the code, I came to know that zookeeper was returning the address of
hmaster as localhost.localdomain, so the client was trying to search
for
the hmaster locally. When I changed the |/etc/hosts| file of my local
machine from where i am running the java client as:
|<ip of the master> localhost.localdomain|
then it worked fine.
However, I think that this is not the right way. I think I have to
change the addresses somewhere in the configuration of zookeeper, but
I did
not get it.
please help
thanks
