Github user zjffdu commented on the issue: https://github.com/apache/zeppelin/pull/3055 Actually we already import this when initialize spark interpreter. https://github.com/apache/zeppelin/blob/master/spark/spark-scala-parent/src/main/scala/org/apache/zeppelin/spark/BaseSparkScalaInterpreter.scala#L171 The problem is that we would still hit this kind of error when run the tutorial note of bank data. This is due to an issue scala 2.10 (SI-6649)[https://issues.scala-lang.org/browse/SI-6649]. This error doesn't' happen before just because we split code into lines and interpret it line by line. But as I mentioned before, interpret it line by line is not a correct approach. The good news is that it only affect scala 2.10.
