在将值从一个hbase表传输到另一个hbase表时出现以下错误。代码在从hbase表传输到文件输出时工作正常。

驾驶员等级：

// Mapper
        TableMapReduceUtil.initTableMapperJob(
                mailsTable,
                scan,
                SimHashMapper.class,
                Text.class, Text.class,
                job);
        //reducer
        String targetTable="old_64bit";
       TableMapReduceUtil.initTableReducerJob(
                targetTable,        // output table
                SimHashReducer.class,    // reducer class
                job);
return job;

Map器类是：

public static class SimHashMapper extends
            TableMapper<Text, Text> {

        public void map(ImmutableBytesWritable row, Result value,
                Context context) throws InterruptedException, IOException {
                         .......
           context.write(new Text(s),new Text(t));

减速器等级为：

public static class SimHashReducer extends
            TableReducer<Text, Text,ImmutableBytesWritable> {

        public void reduce(Text key, Text values, //values is a single Text value
                Context context) throws IOException, InterruptedException {

            Put put = new Put(Bytes.toBytes(values.toString()));
            put.add(Bytes.toBytes("64_bit_fingerprint"),Bytes.toBytes(""),Bytes.toBytes(values.toString()));
            //context.write(new ImmutableBytesWritable(Bytes.toBytes("old_64bit")),put);

           context.write(null, put);

提前谢谢！！！
