Storm developers must provide their own Kerberos keytab and principal name for
storm-hdfs and storm-hbase connectors in topologies
that run on secure clusters. The Config object must contain the storm
keytab file and the principal name, as shown in the following example:
Config config = new Config();
...
config.put("storm.keytab.file","$keytab");
config.put("storm.kerberos.principal","$principal");
StormSubmitter.submitTopology("$topologyName",config,builder.createTopology());
