Tsz Wo Nicholas Sze commented on HADOOP-10741:
----------------------------------------------
Andrew, if you agreed that the new library is useful, why not adding it to
Hadoop? This is similar to the new client proposed in HADOOP-10389, would you
suggest it to live on github or elsewhere?
> A lightweight WebHDFS client library
> ------------------------------------

> Key: HADOOP-10741
> URL: https://issues.apache.org/jira/browse/HADOOP-10741
> Project: Hadoop Common
> Issue Type: New Feature
> Components: tools
> Reporter: Tsz Wo Nicholas Sze

> One of the motivations for creating WebHDFS is for applications connecting to
> HDFS from outside the cluster. In order to do so, users have to either
> # install Hadoop and use WebHdfsFileSsytem, or
> # develop their own client using the WebHDFS REST API.
> For #1, it is very difficult to manage and unnecessarily complicated for
> other applications since Hadoop is not a lightweight library. For #2, it is
> not easy to deal with security and handle transient errors.
> Therefore, we propose adding a lightweight WebHDFS client as a separated
> library which does not depend on Common and HDFS. The client can be packaged
> as a standalone jar. Other applications simply add the jar to their
> classpath for using it.
