Vinod Kumar Vavilapalli updated HDFS-6401:
------------------------------------------

Not much going on here for a long time, dropping from 2.8.0.
Not putting any target-version either anymore, let's target this depending on when there is patch activity.

> Key: HDFS-6401
> URL: https://issues.apache.org/jira/browse/HDFS-6401
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 2.0.0-alpha, 3.0.0-alpha1
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Priority: Critical
>
> Webhdfs only uses the network failover policy if HA is enabled. The policy adds retries for exceptions such as connect failures which are always useful. The proxy also provides support for standby and retriable exceptions which are required for HA IP-based failover because the client does not know if the NN is HA capable or not.
