Subject [jira] [Updated] (HDFS-11027) libhdfs++: Don't retry if there is an authentication failure
Date Wed, 19 Oct 2016 21:53:58 GMT

     [ https://issues.apache.org/jira/browse/HDFS-11027?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

James Clampffer updated HDFS-11027:
    Attachment: HDFS-11027.HDFS-8707.000.patch

Uploading patch on behalf of [~xiaowei.zhu], can't assign to him either until permissions
issues are sorted out.

Patch looks good to me, +1.

> "Authentication failed" status falls into the general !status.ok() block in the HA retry
policy so it will keep attempting to failover.  If the client isn't kerberized, or doesn't
have the right ticket it should give up and return a meaningful error message (right now it
returns a generic bad connection failure string).
> Wouldn't hurt to check the FixedDelayRetryPolicy to make sure that doesn't also keep
attempting to retry in the same way.  I suspect it does.
