------------------------------------

             Summary: Flaky Test:  BucketedWriteWithoutHiveSupportSuite
                 Key: SPARK-23894
                 URL: https://issues.apache.org/jira/browse/SPARK-23894
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Imran Rashid


Flaky test observed here: https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/88991/

I'll attach a snippet of the unit-tests logs, for this suite and the preceeding one.  Here's a snippet of the exception.

I doubt this is actually because of BucketedWriteWithoutHiveSupportSuite.  I think it has something more to do with {{SparkSession}} 's lazy evaluation of {{SharedState}} doing something funny with the way we setup the test spark context etc ... though I don't really understand it yet.
