Pig スクリプトを作成しようとしています。ローカル モードでは正常に動作していますが、疑似分散モードで Pig を起動するとエラーが発生します。スクリプトは次のとおりです。
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'
次のエラーが表示されます。

ファイルは HDFS に存在し、jar を登録せずPigStorage()、UDF の代わりに使用する別のスクリプトは正常に動作しています。jar を登録して UDF を呼び出す他の方法はありますか?
