Andrew Wang commented on HDFS-11431:
------------------------------------
Hi Kai,
This JIRA (HDFS-11431) adds hadoop-hdfs as a dependency of hadoop-hdfs-client
(and thus also hadoop-client). This pulls all the server JARs back in. It was
committed as a quick fix to get 2.8.0 released.
As you noted, HDFS-11538 is intended as a better long term solution that moves
CFPP to hadoop-hdfs-client, so it no longer needs to pull in the full
hadoop-hdfs dependency (the server-side jar).
This also highlights a significant lack of testing of the hdfs client artifact.
The hdfs client split didn't also split the tests, so we have essentially no
test coverage for the client module by itself. It'd be great for HDFS-11538 to
include hdfs client unit tests to help address this.

> The {{hadoop-hdfs-client-2.8.0.jar}} file does include the
> {{ConfiguredFailoverProxyProvider}} class. This breaks client applications
> that use this class to communicate with the active NameNode in an HA
> deployment of HDFS.
