             Summary: Multiple token access is supported in HA noZK KMS 
environment
                 Key: HADOOP-18864
                 URL: https://issues.apache.org/jira/browse/HADOOP-18864
             Project: Hadoop Common
          Issue Type: Improvement
          Components: kms
    Affects Versions: 3.3.6
            Reporter: kuper

When there is no configuration of ZooKeeper synchronization for secrets on the 
KMS server (hadoop.kms.authentication.signer.secret.provider is null), the YARN 
MapReduce job fails to run successfully. The reason is that the KMS returns an 
error "invalidToken" as it cannot find the corresponding token in the cache.
