Installation of hbase and hadoop went fine .

ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3
retries

What version of HBase are you using?
Are you sure that your HBase Master is running?
This exception is fired when there is not an available node or if you
are running the cluster in local mode, the current directory for the
master is not available.
So, if you running your cluster locally, check its local directory
If you are running in pseudo or distributed mode, check if its HDFS
directory is available
Did you check if your HDFS cluster is running?
