Log和get方法的问题

您好，我在本地运行了您的代码，想直接使用您已经训练好的模型，但是暂时遇到了2个问题，想向您请教一下：
代码中使用了很多log.error()方法，我添加了import org.apache.log4j.Logger;用来初始化对象log，如private static final Logger log = LogManager.getLogger(CategoryUtils.class);，但是目前项目中log.error()方法仍然报错，不知道您使用的是哪个log？
代码中使用了很多getXXXX( )方法，如getAppName()、getMasterUrl()、getDependenceJar()、getDependenceJar()等等，但是并没有定义具体内容，我这里大多报错了这类方法，这些定义可以省略吗？谢谢
另：为提高共同效率，大佬可以加我一下微信吗？cghcgh3333，有偿～
windows下使用idea运行项目一直提示model下的part-00000 does not exist

我因为业务需要偶然发现了这个项目对spark和hadoop都是一窍不通
为了运行代码我已经在虚拟机装过了spark以及windows下装过了hadoop，但是运行代码会提示：org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 3.0 failed 4 times, most recent failure: Lost task 0.3 in stage 3.0 (TID 15, 10.80.70.31, executor 0): java.io.FileNotFoundException: File file:/D:/projects/my-project/product-category-predict-master/model/bayes/metadata/part-00000 does not exist
我确认了项目下是有文件的
请问这要怎么处理才能运行
product.dict 有什么用吗? 分词结果的term中该是什么是什么，product.dict没有生效呀
