> Before IOContext problem is found in MapTran when spark rdd cache is enabled in HIVE-8920.
> so we disabled rdd cache in MapTran at [SparkPlanGenerator|https://github.com/kellyzly/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/spark/SparkPlanGenerator.java#L202]. The problem is IOContext seems not initialized correctly in the spark yarn client/cluster mode and caused the exception like
