自定义SerDe的配置单元异常

Question

I'm trying to use hive with a custom SerDe and StorageHandler classes. When I try to run a hive query using the new SerDe, I get the following exception with no other details.

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

I tried logging information inside the StorageHandler and it seems it was created successfully but the SerDe initialize function wasn't called.

Is there an obvious reason for this exception or an easy way to debug it ?

Thanks

不好的是，我只查看了hive CLI中生成的日志，没有检查/tmp/$user/hive.log ，问题是生成的jar中缺少类。
