Java 来自TaskAttemptContext的JobConf

我试图在自定义TextInputFormat类中获得JobConf

我该怎么做

Hadoop 0.20 API请满足Amazon EMR要求

TaskAttemptContext有一个getJobConf方法，该方法返回JobConf：

org.apache.hadoop.mapred.TaskAttemptContext.getJobConf

public RecordReader<LongWritable,Text> createRecordReader(InputSplit split, TaskAttemptContext context) {
 return new XmlInputFormat(split, ...jobconf...);
}
