Make sure that we have default-jdk and default-jre installed on our system..If not install both and restart the cassandra service..

I have the HDP 2.4 setup..Since there is no builtin cassandra service,I have added cassandra to my cluster from the following link.. https://github.com/Symantec/ambari-cassandra-service..Installation results in a warning in one of my host,but the rest all were successful.But I am unable to start my cqlsh shell now..Its showing Connection error: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('127.0.0.1', 9042)]...Also noticed some critical errors in ambari Connection failed: [Errno 111] Connection refused to node1.domain:7000.

By default my zookeeper.znode.parent value which comes under hbase-site.xml is /hbase/unsecure and with these values Hbase application ends up in errors when we start the ambari applications.But I tried changing the value from /hbase/unsecure to /hbase which eliminated the errors all of a sudden..But now I am facing the Can't get locations/connection exception error when I am trying to access Hbase from a client through java.Any help would be thankful.

JDBC driver class listed in my Hive configuration is com.mysql.jdbc.Driver.But all the documentation saying that we have to use org.apache.hive.jdbc.HiveDriver.I tried with both of the JDBC Driver class but failed to create a database inside Hive remotely from java.
