             Summary: Translation of LocalResources via Tez plan serialization can be lossy
                 Key: TEZ-2397
                 URL: https://issues.apache.org/jira/browse/TEZ-2397
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.4.0
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


Happens when there's no port information. The way we serialize a YarnURL into a string causes the reconstructed path to include the port as -1, which is an invalid URL. Path/URL reconstruction from this causes the hostname to be lost.
This is problematic on clusters running HDFA HA - since there's no host:port information, only a service name. I'd imaging it'll be a problem for viewfs as well.
