帮忙看下为什么自定义的InputFormat分隔字符没有效果？

[zs1602001]

文本列之间分隔符为“||”
以下是java代码（参考网上的代码）：
package com.pack.conf;

import java.io.IOException;
import java.util.List;

import org.apache.hadoop.io.LongWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapred.FileSplit;
import org.apache.hadoop.mapred.InputSplit;
import org.apache.hadoop.mapred.JobConf;
import org.apache.hadoop.mapred.JobConfigurable;
import org.apache.hadoop.mapred.LineRecordReader;
import org.apache.hadoop.mapred.RecordReader;
import org.apache.hadoop.mapred.Reporter;
import org.apache.hadoop.mapred.TextInputFormat;


public class MCInputFormat extends TextInputFormat{

public RecordReader<LongWritable, Text> getRecordReader(
InputSplit genericSplit, JobConf job, Reporter reporter)
throws IOException {

reporter.setStatus(genericSplit.toString());
return new LineRecordReader(job, (FileSplit) genericSplit);
}

public static class MCRecordReader implements
RecordReader<LongWritable, Text> {
LineRecordReader reader;
Text text;


public MCRecordReader(LineRecordReader reader){
this.reader = reader;
text = reader.createValue();
}

@Override
public void close() throws IOException {
reader.close();

}

@Override
public LongWritable createKey() {
return reader.createKey();
}

@Override
public Text createValue() {

return new Text();
}

@Override
public long getPos() throws IOException {
return reader.getPos();
}

@Override
public float getProgress() throws IOException {
return reader.getProgress();
}

@Override
public synchronized boolean next(LongWritable key, Text value) throws IOException {
while (reader.next(key, text)) {
String strReplace = text.toString().toLowerCase().replaceAll("\\|\\|", "\001");
Text txtReplace = new Text();
txtReplace.set(strReplace);
value.set(txtReplace.getBytes(), 0, txtReplace.getLength());
return true;
}
return false;
}
}

}


按照教程说的将jar包入到了hive的lib目录下，然后在Hive里面创建表时
这样指定了输入方式和输出方式，
.......
stored as INPUTFORMAT 'com.pack.conf.MCInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat' ;


但是在Hive里查询该表时，发现并没有成功分隔文本，

所以想请教一下，是哪里出了问题呢？
