How to load udf jars in flink program

[liujiangang]

      We are using per-job to load udf jar when start job. Our jar file is
in another path but not flink's lib path. In the main function, we use
classLoader to load the jar file by the jar path. But it reports the
following error when job starts running.
      If the jar file is in lib, everything is ok. But our udf jar file is
managed in a special path. How can I load udf jars in flink program with
only giving the jar path?

我们是这么做的，你们可以试一下。用-yt指定jar所在的目录，-C将jar添加进classpath

例如：flink run -m yarn-cluster -yt /external/libs  -C file:///external/libs/func1.jar -C file:///external/libs/func2.jar

/external/libs 是指启动flink程序所在机器的目录吗？你们在程序里也是通过classLoader加载的jar包然后注册udf吗？

         我刚才简单试了一下，将jar包放在/tmp下，会报下面的问题：
