-------------------------------------

             Summary: Namenode should throw a RetryStartFileException exception instead of making a synchronous call to kms incase of cache miss.
                 Key: HDFS-12124
                 URL: https://issues.apache.org/jira/browse/HDFS-12124
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: kms
    Affects Versions: 2.7.0
            Reporter: Rushabh S Shah
            Assignee: Rushabh S Shah


The namenode should throw a RetryStartFileException exception instead of making a synchronous call to kms incase of cache miss. Other kms issues (like kms getting stalled, issues talking to underlying kms) will block all the namenode handler threads.
