> Key: HBASE-22162
> URL: https://issues.apache.org/jira/browse/HBASE-22162
> Project: HBase
> Issue Type: Bug
> Components: hadoop2, hbase-connectors, java
> Affects Versions: 1.2.5
> Environment: Google Cloud VM
> Reporter: Melanka
> Priority: Blocker
>
> I have installed Hadoop single node [http://intellitech.pro/tutorial-hadoop-first-lab/ |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.
> {code:java}
> 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: Connection refused: db-2.c.xxx-dev.internal/xx.xx.0.21:16201, details=row 'xxx,00000000001:1553904000000,99999999999999' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=db-2.c.xxx-dev.internal,16201,1553683263844, seqNum=-1{code}

> 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.
