--------------------------------
Summary: Create a separate jar for hdfs-client
Key: HDFS-6200
URL: https://issues.apache.org/jira/browse/HDFS-6200
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Haohui Mai
Assignee: Haohui Mai
Currently the hadoop-hdfs jar contain both the hdfs server and the hdfs client.
As discussed in the hdfs-dev mailing list
(http://mail-archives.apache.org/mod_mbox/hadoop-hdfs-dev/201404.mbox/browser),
downstream projects are forced to bring in additional dependency in order to
access hdfs. The additional dependency sometimes can be difficult to manage for
projects like Apache Falcon and Apache Oozie.
This jira proposes to create a new project, hadoop-hdfs-cliient, which contains
the client side of the hdfs code. Downstream projects can use this jar instead
of the hadoop-hdfs to avoid unnecessary dependency.
Note that it does not break the compatibility of downstream projects. This is
because old downstream projects implicitly depend on hadoop-hdfs-client through
the hadoop-hdfs jar.
