-----------------------------------------
[~daryn] - any comments on the above? I'd really like to get this resolved ASAP.
> RPC client doesn't use per-connection conf to determine server's expected
> Kerberos principal name

> Key: HADOOP-10070
> URL: https://issues.apache.org/jira/browse/HADOOP-10070
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.2.0
> Reporter: Aaron T. Myers
> Assignee: Aaron T. Myers
> Attachments: HADOOP-10070.patch, HADOOP-10070.patch,
> TestKerberosClient.java
>
>
> Currently, RPC client caches the {{Configuration}} object that was passed in
> to its constructor and uses that same conf for every connection it sets up
> thereafter. This can cause problems when security is enabled if the
> {{Configuration}} object provided when the first RPC connection was made does
> not contain all possible entries for all server principals that will later be
> used by subsequent connections. When this happens, it will result in later
> RPC connections incorrectly failing with the error "Failed to specify
> server's Kerberos principal name" even though the principal name was
> specified in the {{Configuration}} object provided on later RPC connection
> attempts.
> I believe this means that we've inadvertently reintroduced HADOOP-6907.
