--------------------------------------------
Summary: 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
Assignee: Mohammad Kamrul Islam
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.
