Looks like your RegionServer process might have died if you can't
connect to its RPC port.
Did you look in the RegionServer log for any mention of an ERROR or
FATAL log message?

I have installed Hadoop single node

a Java agent to connect to the Hbase. After a random time period Hbase stop
working and the java agent gives following error message.

Here are the Hbase and zookeeper logs

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>

<name>hbase.zookeeper.property.clientPort</name>

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.
