      Description

      I deployed Hadoop 3.2.2 cluster with KMS in HA using LoadBalancingKMSClientProvider with Kerberos authentication. KMS instances are configured with ZooKeeper for storing the shared secret.

      I have created an encryption key and an encryption zone in `/test` directory and executed `randomtextwriter` from mapreduce examples passing it a sub-directory in the encryption zone:

      hadoop jar hadoop-mapreduce-examples-3.2.2.jar randomtextwriter /test/randomtextwriter
      

      Unfortunately the job keeps failing with errors like:

      java.io.IOException: org.apache.hadoop.security.authentication.client.AuthenticationException: org.apache.hadoop.security.token.SecretManager$InvalidToken: token (kms-dt owner=packer, renewer=packer, realUser=, issueDate=1615146155993, maxDate=1615750955993, sequenceNumber=1, masterKeyId=2) can't be found in cache

      I've injected a few logs on my own and it seems that the client gets 403 on "decrypt" request:

      and the exception is thrown from: 

      org.apache.hadoop.crypto.key.kms.KMSClientProvider#call(java.net.HttpURLConnection, java.lang.Object, int, java.lang.Class<T>, int)
         ...

         HttpExceptionUtils.validateResponse(conn, expectedResponse);
         LOG.info("DD: Response passed validation");
         ...

      It seems that the delegation token is not shared between both KMS instances and when the request hits the KMS instance that does not have the delegation token it responds with `AuthenticationException`, from:

      org.apache.hadoop.security.token.delegation.web.DelegationTokenAuthenticationHandler#authenticate
      

      which makes the client not retry the request with the other KMS instance.

      When I shutdown one of the KMS instances before launching the job then the job succeeds.

      I thought it might have something to do with https://issues.apache.org/jira/browse/HADOOP-16199 so I tried the same setup with 3.3.0 but, unfortunately, with the same result.

      I also run exactly the same job on CDH 5.16.1, which is my current deployment and which I am considering to replace with 3.2.2. The job did succeed on CDH 5.16.1.

      I can provide more logs if that is needed, the issue is deterministic in my environment.

       

      Here is configuration of one of the KMS instances (they are both identical - down to the host part of the KMS principal):

       and here is how KMS is configured in `core-site.xml` in my cluster:

        <name>hadoop.security.key.provider.path</name>
        <value>kms://http@node-10-9-4-175.bdcluster;node-10-9-4-140.bdcluster:16000/kms</value>
      </property>
