我正在将emr作业从emr 3.7.0迁移到5.13.0。我们在hive脚本中使用brickhouse udf函数。在EMR 5.13.0上，我在kryo库中遇到 stackoverflow错误。潜水深入后，我发现这个问题（link）已于2015年修复到kryo图书馆。 我在hive 2.3.2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

其次是

此堆栈跟踪包含代码（link），这些代码作为修复程序从kryo库中删除。
