Description

In my application,i use multi threads. Each thread has a SparkSession and use SparkSession.sqlContext.udf.register to register my udf. Sometimes there throws exception like this:

java.lang.IllegalArgumentException: Error while instantiating 'org.apache.spark.sql.hive.HiveSessionStateBuilder':
