I am seeing following exception while submitting Oozie job on sandbox environment. Please help.

JA002: Unauthorized connection for super-user: oozie from IP 127.0.0.1 Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): Unauthorized connection for super-user: oozie from IP 127.0.0.1 at org.apache.hadoop.ipc.Client.call(Client.java:1468) at org.apache.hadoop.ipc.Client.call(Client.java:1399) at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:232) at com.sun.proxy.$Proxy39.getDelegationToken(Unknown Source) at org.apache.hadoop.yarn.api.impl.pb.client.ApplicationClientProtocolPBClientImpl.getDelegationToken(ApplicationClientProtocolPBClientImpl.java:306) ... 30 more

It looks like that you need to add value “localhost” or "127.0.0.1" for parameter hadoop.proxyuser.oozie.hosts in /etc/hadoop/conf/core-site.xml. Once you add this through ambari-ui, please save and restart the Oozie service.

<property>
      <name>hadoop.proxyuser.oozie.hosts</name>
      <value>127.0.0.1,localhost,sandbox.hortonworks.com</value>
</property>

Hope this helps you.
