[jira] [Created] (SPARK-19508) Improve error message when binding
service fails
Liang-Chi Hsieh created SPARK-19508:
---------------------------------------
Summary: Improve error message when binding service fails
Key: SPARK-19508
URL: https://issues.apache.org/jira/browse/SPARK-19508
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.1.0
Reporter: Liang-Chi Hsieh
Priority: Trivial
Utils provides a helper function to bind service on port. This function can bind the service to a random free port. However, if the binding fails on a random free port, the retrying and final exception messages look confusing.
