   The build is failing but not at changes I have made:
   
   ```
   error] /home/jenkins/workspace/SparkPullRequestBuilder/mllib/src/test/scala/org/apache/spark/ml/util/MLTestingUtils.scala:184: type mismatch;
   [error]  found   : Function0[Int] (in scala) 
   [error]  required: Function0[?]   (in org.apache.spark.api.java.function) 
   [error]     val sampleUDF = udf(sample)
   ```
   
   @HyukjinKwon How should we proceed to isolate the failure from my changes?
