Subject [jira] [Created] (HDFS-6329) WebHdfs does not work if HA is enabled on NN but logical URI is not configured.
Date Fri, 02 May 2014 22:59:14 GMT
Kihwal Lee created HDFS-6329:
--------------------------------

             Summary: WebHdfs does not work if HA is enabled on NN but logical URI is not
configured.
                 Key: HDFS-6329
                 URL: https://issues.apache.org/jira/browse/HDFS-6329
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.4.0
            Reporter: Kihwal Lee
            Priority: Blocker


After HDFS-6100, namenode unconditionally puts the logical name (name service id) as the token
service when redirecting webhdfs requests to datanodes, if it detects HA.

For HA configurations with no client-side failover proxy provider (e.g. IP failover), webhdfs
does not work since the clients do not use logical name.
