My spark cluster version is spark-2.2.0. I get an error when I submit a job to zeppelin:
com.fasterxml.jackson.databind.JsonMappingException: Incompatible Jackson version: 2.8.11–1
then, I changed Jackson version to 2.6.5.but it throws another exception:
org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 4 times, most recent failure: Lost task 0.3 in stage 0.0 (TID 3, 192.168.1.123, executor 1): java.io.IOException: Connection from /192.168.1.131:46017 closed.
192.168.1.131 :46017 is spark driver。 192.168.1.123 is executor 1。
