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.
