MapReduce连接Hbase时报错及处理

我的Map class如下:


package com.hbasepackage;


import java.io.IOException;


import org.apache.hadoop.hbase.client.Result;


import org.apache.hadoop.hbase.io.ImmutableBytesWritable;


import org.apache.hadoop.hbase.mapreduce.TableMapper;


import org.apache.hadoop.hbase.util.Bytes;


import org.apache.hadoop.io.IntWritable;


import org.apache.hadoop.io.Text;


import com.google.common.primitives.*;


@SuppressWarnings("unused")


public class TestMapper extends TableMapper<Text, IntWritable>{


@Override


protected void map(ImmutableBytesWritable rowKey, Result columns, Context context)


throws IOException, InterruptedException {


try {


// get rowKey and convert it to string


String inKey = new String(rowKey.get());


// set new key having only date


String oKey = inKey.split("#")[0];


// get sales column in byte format first and then convert it to string


// (as it is stored as string from hbase shell)


byte[] bSales = columns.getValue(Bytes.toBytes("cf1"), Bytes.toBytes("sales"));


String sSales = new String(bSales);
