Could not resolve the DNS name of slave2:60020
I have a HBase cluster on AWS. I have written few REST services which are
supposed to connect to this HBase cluster and get some data.
My configuration is as below :
1. Java code, eclipse, tomcat running on my desktop
2. HBase cluster, Hadoop cluster sitting on AWS
3. Can connect to HBase cluster, Hadoop cluster ONLY THROUGH VPN
Whenever web service tries to do ANY operation on HBase, it throws Could
not resolve the DNS name of slave2:60020 error with following stack trace.
java.lang.IllegalArgumentException: Could not resolve the DNS name of
slave2:60020

In hbase-site.xml file I have given IP address of HBase master and in
core-site.xml file IP address of namenode is given.
Has anyone faced this type of problem? Why this problem arises?
I have posted same question on Stack overflow but no one replied hence
posting question here.
Request you to please help.

Oh. 0.90.6 is VERY old. Any chance for you to upgrade a more recent version
like CDH4 or even CDH5 (HBase 0.98)?

Re: Could not resolve the DNS name of slave2:60020
Posted by Qiang Tian <ti...@gmail.com>.
see https://issues.apache.org/jira/browse/HBASE-3556
it looks you are using a very old release? 0.90 perhaps?

Re: Could not resolve the DNS name of slave2:60020
Posted by Chandrashekhar Kotekar <sh...@gmail.com>.
This is how /etc/hosts file looks like on HBase master node
ubuntu@master:~$ cat /etc/hosts
10.78.21.133 master
#10.62.126.245 slave1
#10.154.133.161 slave1
10.224.115.218 slave1
10.32.213.195 slave2
and the code which actually tries to connect is as shown below:
hTableInterface=hTablePool.getTable("POINTS_TABLE");

Hi Chandrash,
What do you have in your /etc/hosts? Can you also share the piece of code
where you are doing the connection to HBase?
Thanks,
