> Key: HDFS-8852
> URL: https://issues.apache.org/jira/browse/HDFS-8852
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: documentation
> Reporter: Hong Dai Thanh
> Assignee: Ajith S
> Labels: newbie
> Fix For: 2.7.2
>
> Attachments: HDFS-8852.2.patch, HDFS-8852.patch

>
> In the [latest version of the
> documentation|http://hadoop.apache.org/docs/current2/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html#Simple_Coherency_Model],
> 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.”
>
> However, as far as I know, HDFS has supported append write since 0.21, based
> on [HDFS-265|https://issues.apache.org/jira/browse/HDFS-265] and [the old
> version of the documentation in
> 2012|https://web.archive.org/web/20121221171824/http://hadoop.apache.org/docs/hdfs/current/hdfs_design.html#Appending-Writes+and+File+Syncs]
> 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)
