When looking at the details of the Travis CI build, I found the first error
messages to be:
-------------------------------------------------------------------------
Begin of error
[ERROR]
/home/travis/build/apache/flink/flink-staging/flink-ml/src/main/scala/org/apache/flink/ml/nn/KNN.scala:23:
error: object DataSetUtils is not a member of package
org.apache.flink.api.scala
[INFO] import org.apache.flink.api.scala.DataSetUtils._
[INFO] ^
[ERROR]
/home/travis/build/apache/flink/flink-staging/flink-ml/src/main/scala/org/apache/flink/ml/nn/KNN.scala:170:
error: value zipWithUniqueId is not a member of
org.apache.flink.api.scala.DataSet[T]
--------------------------------------------------------------------------------------
end of errors
There are additional errors that follow, but those are the first two errors
that popped up. The import of DataSetUtils._ was adopted from @chiwanpark,
maybe he has an idea of what is the cause of the error. I unfortunately was
not using Travis CI from the start, but will try to use it from now on.
