             Summary: Improve appendToFile command: support appending on file with new block
                 Key: HDFS-16716
                 URL: https://issues.apache.org/jira/browse/HDFS-16716
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: guojunhao


HDFS client DistributedFileSystem#append supports appending to a file with optional create flags.

However, appendToFile command only supports the default create flag APPEND so that append on EC file without NEW_BLOCK create flag is not supported.

Thus, it's necessary to improve appendToFile command by adding option -n for it. Option -n represents that use NEW_BLOCK create flag while appending file.
