Arpit Agarwal resolved HDFS-8177.
---------------------------------
Resolution: Not A Problem
Hi [~bharath.r25], HDFS supports single writer at a time for a given file.
Feel free to post to the mailing list with detailed exceptions if you have
further questions. I am resolving the Jira.
> When the dfs -appendToFile - /<hadoop-file-path> is used concurrently in
> different process simultaneously pointing to the same hadoop file. It
> produces a exception stating file cannot be created since File already exists
