HBase分布式集群环境搭建成功后，连续4、5天实验客户端Map/Reduce程序开发，这方面的代码网上多得是，写个测试代码非常容易，可是真正运行起来可说是历经挫折。下面就是我最终调通并让程序在集群上运行起来的一些经验教训。
一、首先说一下我的环境：
1，集群的环境配置请见这篇博文。
2，开发客户机环境：操作系统是CentOS6.5，JDK版本是1.7.0-60，开发工具是Eclipse（原始安装是从google的ADT网站下载的ADT专用开发环境，后来加装了Java企业开发的工具，启动Flash还是ADT的：））。
3，etc/hosts文件添加了集群的所有主机。
二、必要准备工作：
1，java类库准备：从集群中scp复制了Hadoop/share下所有文件，hbase/lib目录下的所有文件到开发机的/home/username/lib目录下备用(其中username是开发用户名称)，打开eclipse，选择菜单window->Preferences,
在左侧树形菜单中导航至Java--Build Path--User Libraries，我添加了3个User Library，“hadoop-common”，“hadoop-yarn”，“hbase”
然后分别添加如下（这是User Libraries的导出文件，可以在上面的界面中导入）的jar包。

注：这个很有可能并不是运行Hbase Map/Reduce任务需要的最精简的类库，恕我没有逐一测试。
2，新建一个Java/Application，我的名字就叫hbase1，然后在项目project视图中点击右键，选择“Build Path”--“Add Libraries...”--选择“User Library”，然后选中上面添加的三个User Library。
3，复制集群的三个配置文件到项目的src目录下，这三个配置文件是：
core-site.xml hdfs-site.xml yarn-site.xml
三、编写代码，这里基本按照我所遇挫折过程逐步完善代码（缺少类库之类的就略掉了）：
1，遭遇空指针错误--reverseDNS
主文件内容：
/**
* @author gzg
*

public class Test1 {
/**
* @param args
* @throws IOException
* @throws ZooKeeperConnectionException
* @throws MasterNotRunningException
*/
Configuration conf=null;
public static void main(String[] args) {
try {
new TestHBaseMapred().run(false);
} catch(yh.utils.system.CommandError cep){
cep.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
TestHBaseMapRed.java内容：
public class TestHBaseMapred {
public void run(boolean toFile) throws ClassNotFoundException, IOException, InterruptedException{
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
//设置zookeeper的地址s
conf.set("hbase.zookeeper.quorum", "zk1,zk2,zk3");
//此设置好像没用
conf.set("hadoop.job.user", "hadoop");
org.apache.hadoop.mapreduce.Job job=null;
String tmpTable = "_mrtest1";
yh.utils.ElapsedTimeMeasure etm=yh.utils.ElapsedTimeMeasure.createAndStart();
try {
job = Job.getInstance(conf);
job.setJobName("count meter");
if(toFile==false){
HBaseUtil.dropTable(conf, tmpTable);
HBaseUtil.createTable(conf, tmpTable, "c");
job.setOutputFormatClass(org.apache.hadoop.hbase.mapreduce.TableOutputFormat.class);
job.getConfiguration().set(org.apache.hadoop.hbase.mapreduce.TableOutputFormat.OUTPUT_TABLE, tmpTable);
//
job.setReducerClass(TblReduce.class);
}else{
job.setOutputFormatClass(org.apache.hadoop.mapreduce.lib.output.TextOutputFormat.class);
Path op = new Path("result");
org.apache.hadoop.mapreduce.lib.output.TextOutputFormat.setOutputPath(job, op);
//
job.setReducerClass(TxtReduce.class);
}
Scan scan = new Scan();
scan.addFamily(Bytes.toBytes("c"));
org.apache.hadoop.hbase.mapreduce.TableMapReduceUtil.initTableMapperJob("dzdl_t1",scan,TblMap.class ,Text.class,LongWritable.class,job);
job.waitForCompletion(true);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("time elapsed :"+etm.stop().toString());
}
public static class TblMap extends org.apache.hadoop.hbase.mapreduce.TableMapper<Text, LongWritable>{
@Override
protected void map(ImmutableBytesWritable key,Result result,org.apache.hadoop.mapreduce.Mapper.Context ctx) throws IOException, InterruptedException{
Cell c=result.getColumnLatestCell(Bytes.toBytes("c"), Bytes.toBytes("col3"));
String col= Bytes.toString(CellUtil.cloneQualifier(c));
Text kv = new Text();
kv.set("count_result");
LongWritable lv = new LongWritable();
lv.set(1);
ctx.write(kv, lv);
//org.apache.log4j.Logger.getRootLogger().info(kv+" : 1");
}
}
public static class TblReduce extends org.apache.hadoop.hbase.mapreduce.TableReducer<Text,LongWritable,ImmutableBytesWritable>{
@Override
protected void reduce(Text key,Iterable<LongWritable> values,Context ctx) throws IOException, InterruptedException{
long t =0;
for(LongWritable v:values){
t+=v.get();
}
byte[] ok=Bytes.toBytes("count_result");
Put p=new Put(ok);
p.add(Bytes.toBytes("c"),key.copyBytes(),Bytes.toBytes(t));
p.add(Bytes.toBytes("c"),Bytes.toBytes("14112896"),Bytes.toBytes(14112896));
ctx.write(new ImmutableBytesWritable(ok),p);
}
}
public static class TxtReduce extends org.apache.hadoop.mapreduce.lib.reduce.LongSumReducer<Text>{
@Override
public void reduce(Text key,Iterable<LongWritable> values,Context ctx) throws IOException, InterruptedException{
long t =0;
for(LongWritable v:values){
t+=v.get();
}
//Put p=new Put(key.copyBytes());
//p.add(Bytes.toBytes("c"),key.copyBytes(),Bytes.toBytes(t));
//ctx.write(new ImmutableBytesWritable(key.copyBytes()),p);
LongWritable l = new LongWritable();
l.set(t);
ctx.write(key,l);
}
}
}
此时运行，会报如下错误：
Exception in thread "main" java.lang.NullPointerException at org.apache.hadoop.net.DNS.reverseDns(DNS.java:92) at org.apache.hadoop.hbase.mapreduce.TableInputFormatBase.reverseDNS(TableInputFormatBase.java:218) at org.apache.hadoop.hbase.mapreduce.TableInputFormatBase.getSplits(TableInputFormatBase.java:184) at org.apache.hadoop.mapreduce.JobSubmitter.writeNewSplits(JobSubmitter.java:493) at org.apache.hadoop.mapreduce.JobSubmitter.writeSplits(JobSubmitter.java:510) at org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:394) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1295) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1292) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1548) at org.apache.hadoop.mapreduce.Job.submit(Job.java:1292) at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1313) at hbase1.TestHBaseMapred.run(TestHBaseMapred.java:82) at hbase1.Test1.main(Test1.java:69)
看错误，不知道为什么需要调用DNS服务，hosts文件好像没有作用， 搜索很久，终于在一个老外的问题里找到答案，conf添加如下设置解决。
conf.set("hbase.nameserver.address","nn1,nn2");
添加后，运行仍会报下面的错无，但是好像并不影响程序继续运行：

2，本地运行的问题。解决了上面的问题，程序终于可以运行了，可是我在rm的web界面中却看不到我提交的任务，再次求助bing，终于找到症结所在，需要添加设置如下：
//此项必须设置，否则程序只是在本地客户端上运行，通过rm的浏览器管理界面看不到！
conf.set("mapreduce.framework.name", "yarn");
3，添加了上面语句后，新的问题又来了，运行程序出现新的错误：

试着设置 job.setJarByClass(Test1.class); 无效。此问题困扰了我两天，难道只能上传到集群集群上运行吗？这样也太不方便了，N久后，终于我有幸找到了小鱼儿的博客 的这篇文章MapReduce提交作业常见问题，终于是找到了解决方法。我采用的是文中所提第三种方法，在程序开始运行前自己首先打包自己，就是调用的是写好的shell文件，这里也贴出来，以下两个文件在和src同级的dist目录中

同时，修改了TestHBaseMapred.run方法签名，传递jar包路径，新的run方法如下：
public void run(String appJarFile,boolean toFile) throws ClassNotFoundException, IOException, InterruptedException{
//org.apache.hadoop.conf.Configuration conf = yh.utils.hbase.HBaseUtil.getConfiguration("zk1,zk2,zk3");
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
conf.set("hbase.zookeeper.quorum", "zk1,zk2,zk3");
conf.set("hadoop.job.user", "hadoop");
conf.set("mapreduce.framework.name", "yarn");
conf.set("hbase.nameserver.address","nn1,nn2");
org.apache.hadoop.mapreduce.Job job=null;
String tmpTable = "_mrtest1";
yh.utils.ElapsedTimeMeasure etm=yh.utils.ElapsedTimeMeasure.createAndStart();
try {
job = Job.getInstance(conf);
job.setJobName("count meter");
//job.setJarByClass(Test1.class);
job.setJar(appJarFile);
if(toFile==false){
HBaseUtil.dropTable(conf, tmpTable);
HBaseUtil.createTable(conf, tmpTable, "c");
job.setOutputFormatClass(org.apache.hadoop.hbase.mapreduce.TableOutputFormat.class);
job.getConfiguration().set(org.apache.hadoop.hbase.mapreduce.TableOutputFormat.OUTPUT_TABLE, tmpTable);
//
job.setReducerClass(TblReduce.class);
}else{
job.setOutputFormatClass(org.apache.hadoop.mapreduce.lib.output.TextOutputFormat.class);
Path op = new Path("result");
org.apache.hadoop.mapreduce.lib.output.TextOutputFormat.setOutputPath(job, op);
//
job.setReducerClass(TxtReduce.class);
}
Scan scan = new Scan();
scan.addFamily(Bytes.toBytes("c"));
org.apache.hadoop.hbase.mapreduce.TableMapReduceUtil.initTableMapperJob("dzdl_t1",scan,TblMap.class ,Text.class,LongWritable.class,job);
job.waitForCompletion(true);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("time elapsed :"+etm.stop().toString());
}
4，在选择写入文件的Reduce方法是，同样遇到权限问题，我采用的解决方法是给所有用户授予了读写权限，这里注意/tmp也要授权，运行时用到
[hadoop@zk1 hbase]$ hdfs dfs -chmod 777 /user [hadoop@zk1 hbase]$ hdfs dfs -chmod 777 /tmp
另外，最后还有一点注意，设置log4j.properties文件中的级别为INFO，不要设置为WARN，否则看不到很多信息，不利于发现错误原因。
# Configure logging for testing: optionally with log file #log4j.rootLogger=WARN, stdout log4j.rootLogger=INFO, stdout # log4j.rootLogger=WARN, stdout, logfile log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n log4j.appender.logfile=org.apache.log4j.FileAppender log4j.appender.logfile.File=target/spring.log log4j.appender.logfile.layout=org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
四、At last，终于大功告成，看看map/reduce的运行过程
