[jira] [Created] (SPARK-25180) Spark standalone failure in Utils.doFetchFile() if nslookup of local hostname fails

Steve Loughran created SPARK-25180:
--------------------------------------

             Summary: Spark standalone failure in Utils.doFetchFile() if nslookup of local hostname fails
                 Key: SPARK-25180
                 URL: https://issues.apache.org/jira/browse/SPARK-25180
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.3.0
         Environment: mac laptop running on a corporate guest wifi, presumably a wifi with odd DNS settings.
            Reporter: Steve Loughran


trying to save work on spark standalone can fail if netty RPC cannot determine the hostname. While that's a valid failure on a real cluster, in standalone falling back to localhost rather than inferred "hw13176.lan" value may be the better option.

note also, the abort* call failed; NPE.
