Tsz Wo Nicholas Sze commented on HDFS-6633:
-------------------------------------------
[~vinayrpet], I agree that it is better to change DataTransferProtocol to
support blocking read. Do you want to work on it? Thank you in advance and
assigning this to you! If you cannot work on it, please feel free to assign
this back to me.
> Support reading new data in a being written file until the file is closed

> When a file is being written, the file length keeps increasing. If the file
> is opened for read, the reader first gets the file length and then read only
> up to that length. The reader will not be able to read the new data written
> afterward.
> We propose adding a new feature so that readers will be able to read all the
> data until the writer closes the file.
