我正在运行带有transform() using子句和python脚本的Hive-on-Tez（Hortonworks HDP-3.1）查询。当我的脚本失败时，我得到的只是java stacktrace：

TaskAttempt 3 failed,info=[Error: Error while running task ( failure ) : attempt_1572037513902_1984_1_00_000006_3:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row

我在任何地方都找不到python stacktrace，也没有在Yarn容器日志中找到。在正常的map-reduce流工作中，我总是得到python stacktrace。

我已经设置了tez.am.log.level = DEBUG，并获得了大量的DEBUG信息，但仍然没有python跟踪。

是否可以通过UDF脚本获取HIVE-Tez查询的python堆栈跟踪？

谢谢！
