Subject [jira] [Commented] (HDFS-11431) hadoop-hdfs-client JAR does not include ConfiguredFailoverProxyProvider

----------------------------------

Hi,

Could anybody help clarify a little bit for me to understand the issue here and the new issue
HDFS-11538 to solve? Thanks!

The issue title said:
bq. hadoop-hdfs-client JAR does not include ConfiguredFailoverProxyProvider

And the description said:
bq. 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.

Since for {{2.8.0}} the jar does include the class so there is no problem for that version
right? But the target and fix versions were marked as {{2.8.0}}, which is why I'm confused.

Anyway, for trunk, this is left to be fixed in HDFS-11538, where we would have an elegant
fix that only moves the needed class into {{hadoop-hdfs-client}} jar but without introducing
the NN server side classes, so we have to refactor the codes in {{ConfiguredFailoverProxyProvider}}.
Right?
