使用XMLLoader加载XML文件时，我收到错误

Question

我正在加载如下：

  A = LOAD'/home/sawanvijay/Datasets/xml/DATA_EMP.xml' USING       org.apache.pig.piggybank.storage.XMLLoader('ROW') AS (M:CHARARRAY);

错误如下所示：

ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1070: Could not resolve org.apache.pig.piggybank.storage.XMLLoader using imports: [, 
org.apache.pig.builtin., org.apache.pig.impl.builtin.]

看来，你没有注册pigybank jar文件。请参阅此处的说明https://cwiki.apache.org/confluence/display/PIG/PiggyBank 注册piggybank jar文件。
