In the latest version of the documentation, and also documentation for all releases with version 2, it’s mentioned that “A file once created, written, and closed need not be changed. “ and “There is a plan to support appending-writes to files in the future.”
Various posts on the Internet also suggests that append write has been available in HDFS, and will always be available in Hadoop version 2 branch.
Can we update the documentation to reflect the current status?
(Please also review whether the documentation should also be updated for version 0.21 and above, and the version 1.x branch)
