[jira] [Created] (SPARK-23468) Failure to authenticate with old shuffle service

Marcelo Vanzin created SPARK-23468:
--------------------------------------

             Summary: Failure to authenticate with old shuffle service
                 Key: SPARK-23468
                 URL: https://issues.apache.org/jira/browse/SPARK-23468
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.3.0
            Reporter: Marcelo Vanzin


I ran into this while testing a fix for SPARK-23361. Things seem to work fine with a 2.x shuffle service, but with a 1.6 shuffle service I get this error every once in a while:

{noformat}
org.apache.spark.SparkException: Unable to register with external shuffle server due to : java.lang.RuntimeException: javax.security.sasl.SaslException: DIGEST-MD5: digest response format violation. Mismatched response.

This is a regression in 2.3 and I have a fix for it as part of the fix for SPARK-23361. I'm filing this separately so that this particular fix is backported to 2.3.
