Subject Re: help needed towards connecting Hbase
Date Fri, 31 Jan 2014 10:08:12 GMT
Hi,
Thanks for taking initiative to help me..
Note : my set up is single node cluster, so
I added a entry in hbase-site.xml
like
<property>
      <name>hbase.zookeeper.quorum</name>
      <value>localhost</value>
</property>
But still almost same error persists
and my /etc/hosts
looks like
127.0.0.1              localhost.localdomain.com          localhost
127.0.0.1              database.companyname.com      database
If you have noted any issue in using hbase-0.96.0-hadoop2 please let me
know it will be very useful
thanks
