Hi, On a secure hadoop cluster, spark shuffle is enabled (spark 1.6.0, shuffle jar is spark-1.6.0-yarn-shuffle.jar). A client connecting using spark-assembly_2.11-1.6.1.jar gets errors starting executors, with following trace.
Could this be due to spark version mismatch ? Any thoughts ? Thanks in advance, 16/10/04 16:12:53 INFO storage.BlockManager: Registering executor with local external shuffle service. 16/10/04 16:12:53 ERROR client.TransportClientFactory: Exception while
