Subject [jira] [Created] (HDFS-6401) WebHdfs should always use the network failover policy
Date Wed, 14 May 2014 17:15:17 GMT
Daryn Sharp created HDFS-6401:

             Summary: WebHdfs should always use the network failover policy
                 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
            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.
