Re: Please help me how and when to catch java.net.ConnectException in case hbase is not running as it goes on connecting with hbase
bq. org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper.exists(
RecoverableZooKeeper.java:172)

The exception showed problem connecting to zookeeper.
Is hbase-site.xml on the classpath of your app ?

If so, please check (and pastebin) zookeeper log.

Providing HBase version would be useful as well.
