             Summary: Expose HdfsDataOutputStreamBuilder to include Spark in LimitedPrivate
                 Key: HDFS-14038
                 URL: https://issues.apache.org/jira/browse/HDFS-14038
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Xiao Chen


In SPARK-25855 / https://github.com/apache/spark/pull/22881#issuecomment-434359237, Spark prefer to create Spark event log files with replication (instead of EC). To do this currently, it has to be done by some casting / reflection, to get a DistributedFileSystem object (or use the {{HdfsDataOutputStreamBuilder}} subclass of it).

We should officially expose this for Spark's usage.
