We enabled kerberos on the cluster, have enabled HA for nimbus and created the kerberos ticket on the commandline in the edgenode with appropriate rights in ranger for the principal. when running a sample topology of wordcount in this manner storm jar myStorm-0.0.1-SNAPSHOT.jar com.storm.test.myStorm.helloStorm /home/BBattin/storm_test/input.txt

we are getting the following error

Exception in thread "main" java.lang.RuntimeException: Could not find leader nimbus from seed hosts [localhost]. Did you specify a valid list of nimbus hosts for config nimbus.seeds at backtype.storm.utils.NimbusClient.getConfiguredClientAs(NimbusClient.java:90) at backtype.storm.StormSubmitter.submitTopologyAs(StormSubmitter.java:225) at backtype.storm.StormSubmitter.submitTopology(StormSubmitter.java:271) at backtype.storm.StormSubmitter.submitTopology(StormSubmitter.java:157) at com.storm.test.myStorm.helloStorm.main(helloStorm.java:24)

please review information in this doc

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.3/bk_secure-storm-ambari/content/ch_secure-st...

Add the following settings to the /etc/storm/conf/storm.yaml configuration file:

nimbus.seeds: <nimbus-host-array>
nimbus.thrift.port: 6667
java.security.auth.login.config: "/etc/storm/conf/client_jaas.conf"
storm.thrift.transport: "backtype.storm.security.auth.kerberos.KerberosSaslTransportPlugin"

where <nimbus-host-array> is an array of hostnames running Nimbus. (The value should come from /etc/storm/conf/storm.yaml.) For example:

nimbus.seeds: ["c6401.ambari.apache.org", "c6402.ambari.apache.org"]

Connect to zookeeper and delete the znode dir related to storm service and restart both "zookeeper" and "storm" service.

/usr/hdp/current/zookeeper-server/bin/zkCli.sh -server <hostname>:2181

[zk: <hostname>:2181(CONNECTED) 0]ls /

[zk: <hostname>:2181(CONNECTED) 0]rmr /storm
