我正在将emr作业从emr 3.7.0迁移到5.13.0。我们在配置单元脚本中使用brickhouse udf函数。在emr5.13.0上，我在kryo库中遇到了stackoverflow错误。深入研究后，我发现这个问题（链接）在2015年被修复到kryo图书馆。我在Hive2.3.2中遇到以下异常。

Caused by: org.apache.hive.com.esotericsoftware.kryo.KryoException: java.lang.IllegalArgumentException: Unable to create serializer "org.apache.hive.com.esotericsoftware.kryo.serializers.FieldSerializer" for class: java.util.concurrent.atomic.AtomicReference

jsonFactory (brickhouse.udf.json.ToJsonUDF)
genericUDF (org.apache.hadoop.hive.ql.plan.ExprNodeGenericFuncDesc)
colExprMap (org.apache.hadoop.hive.ql.exec.SelectOperator)

然后
