Description
Post disabling the kerberos Ambari is not deleting the storm_jaas.conf and client_jaas.conf files from storm conf directory.
Offset lag section in Storm UI is not populating because of the jaas conf.
Unable to get offset lags for kafka. Reason: org.apache.zookeeper.KeeperException$AuthFailedException: KeeperErrorCode = AuthFailed for /brokers/topics/hortonworks/partitions at org.apache.zookeeper.KeeperException.create(KeeperException.java:123) at org.apache.zookeeper.KeeperException.create(KeeperException.java:51) at org.apache.zookeeper.ZooKeeper.getChildren(ZooKeeper.java:1590) at org.apache.curator.shaded.framework.imps.GetChildrenBuilderImpl$3.call(GetChildrenBuilderImpl.java:230) at org.apache.curator.shaded.framework.imps.GetChildrenBuilderImpl$3.call(GetChildrenBuilderImpl.java:219) at org.apache.curator.shaded.RetryLoop.callWithRetry(RetryLoop.java:109) at org.apache.curator.shaded.framework.imps.GetChildrenBuilderImpl.pathInForeground(GetChildrenBuilderImpl.java:216) at org.apache.curator.shaded.framework.imps.GetChildrenBuilderImpl.forPath(GetChildrenBuilderImpl.java:207) at org.apache.curator.shaded.framework.imps.GetChildrenBuilderImpl.forPath(GetChildrenBuilderImpl.java:40) at org.apache.storm.kafka.monitor.KafkaOffsetLagUtil.getLeadersAndTopicPartitions(KafkaOffsetLagUtil.java:323) at org.apache.storm.kafka.monitor.KafkaOffsetLagUtil.getOffsetLags(KafkaOffsetLagUtil.java:257) at org.apache.storm.kafka.monitor.KafkaOffsetLagUtil.main(KafkaOffsetLagUtil.java:126)
Storm's /usr/hdp/current/storm-client/bin/storm-kafka-monitor checks if the storm_jaas.conf exists in storm configuration directory and then uses it.
STORM_JAAS_CONF_PARAM="" JAAS_FILE="${STORM_CONF_DIR}/storm_jaas.conf" if [ -f $JAAS_FILE ]; then STORM_JAAS_CONF_PARAM="-Djava.security.auth.login.config=${JAAS_FILE}" fi
Issue will be resolved if we delete the storm_jaas.conf file manually.
As well storm jaas configs must be readable by world to allow some mpacks work properly.
