Hi all. Hi all.
I'm testing on Spark 2.0.0 and found an issue when using coalesce in my code. The procedure is simple doing a coalesce for a RDD[Stirng], and this happened: java.lang.NoSuchMethodError: org.apache.spark.rdd.RDD.coalesce(IZLscala/math/Ordering;)Lorg/apache/spark/rdd/RDD; The environment is Spark 2.0.0 with Scala 2.11.8, while the application jar is compiled with Spark 1.6.2 and Scala 2.10.6 . BTW, it works OK with Spark 2.0.0 and Scala 2.11.8. So I presume it??s a compatibility issue? __ Best regards.
