I have installed Hadoop single node
http://intellitech.pro/tutorial-hadoop-first-lab/ and Hbase
http://intellitech.pro/hbase-installation-on-ubuntu/ successfully. I am using
a Java agent to connect to the Hbase. After a random time period Hbase stop
working and the java agent gives following error message.
Call exception, tries=7, retries=7, started=8321 ms ago, cancelled=false,
msg=Call to db-2.c.xxx-dev.internal/xx.xx.0.21:16201 failed on connection
exception:
org.apache.hbase.thirdparty.io.netty.channel.AbstractChannel$AnnotatedConnectException:

Here are the Hbase and zookeeper logs
hbase-hduser-regionserver-db-2.log

my hbase-site.xml file is as follows
<configuration>
//Here you have to set the path where you want HBase to store its files.
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
</property>
//Here you have to set the path where you want HBase to store its built in

<value>true</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
</configuration>
when I restart the Hbase it will start working again and stop working after few
days. I am wondering what would be the fix for this.
Thanks.
