issue with coalesce in Spark 2.0.0

[??????]

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?
