I'm testing on Spark 2.0.0 and found an issue when using
coalescein my code.
The procedure is simple doing a
RDD[Stirng], and this happened:
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?
