Major Description
We are running a map reduce/spark job to bulk load hbase data in one of the environment. While running the job, it is not able to connect to hbase zookeeper and throws the following error. We have executed the same job in Titan DEV too but facing the same problem. Please let us know if anyone has faced the same problem before.
Details are,
• Earlier job was failing to connect to localhost/127.0.0.1:2181 hence the property hbase.zookeeper.quorum has been set in map reduce code with particular server details which we got from hbase-site.xml.
• We are using jars of cdh version 5.3.3.
