我正在尝试编写一个pig脚本。我已经成功地在本地模式下工作，但在psudo分布式模式下启动pig时出错。以下是脚本：

register 'myfolder/target/myfunc-with-dependencies.jar';
SET mapred.cache.files /tmp/scripts#scripts,/tmp/my_rules#my_rules;
SET mapred.create.symlink yes;

%default INPUT 'test.seq'
%default OUTPUT 'final.out'
%default TIMEOUT_MS '180000'
%default USE_DEVSHM 'true'

data = load '$INPUT' using com.pack.loaders.MyTextLoader('$TIMEOUT_MS');
STORE data INTO '$OUTPUT'

我得到以下错误：

该文件存在于hdfs和另一个脚本上，该脚本不注册任何jar并使用 PigStorage() 取而代之的是，udf运作良好。有没有其他方法来注册jar并调用udf？
pig日志文件的内容为：
