      Description

      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:

      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.
