hadoop jar 运行hadoop自带wordcount报错
安装完hadoop-2.7.3之后,想试试其自带的wordcount例子,但是一直报下面的错,空间不足。。 但是我都还没开始用,怎么会出这种问题。。我是单机上运行的伪分布式,其他的都能正常运行,hdfs也是正常的,能在其中导入文件啥的,但是就是不能用hadoop jar命名运行![图片说明](https://img-ask.csdn.net/upload/201706/05/1496656412_150716.png)

新手,hadoop上运行wordcount程序报错
运行的环境是:Ubuntu14.04+hadoop2.6.1 用的是virtualBox虚拟机,然后安装了一个master和三个slave节点 hadoop是可以成功启动的,没有任何问题 在Ubuntu安装了eclipse,用java写了word count的程序,源码如下: ``` package wordcount; import java.io.IOException; import java.util.StringTokenizer; import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.fs.Path; import org.apache.hadoop.io.IntWritable; import org.apache.hadoop.io.LongWritable; import org.apache.hadoop.io.Text; import org.apache.hadoop.mapreduce.Job; import org.apache.hadoop.mapreduce.Mapper; import org.apache.hadoop.mapreduce.Reducer; import org.apache.hadoop.mapreduce.lib.input.FileInputFormat; import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat; /** * @author * @version 创建时间:2017年9月9日 上午8:50:51 类说明 */ public class Wordcount { public static class TokenizerMapper extends Mapper<LongWritable, Text, Text, IntWritable> { private final static IntWritable one = new IntWritable(1); private Text word = new Text(); protected void map(LongWritable key, Text value, Mapper<LongWritable, Text, Text, IntWritable>.Context context) throws IOException, InterruptedException { StringTokenizer line = new StringTokenizer(value.toString()); while (line.hasMoreTokens()) { word.set(line.nextToken()); context.write(word, one); } } } public static class IntSumReducer extends Reducer<Text, IntWritable, Text, IntWritable> { private IntWritable result = new IntWritable(); protected void reduce(Text key, Iterable<IntWritable> values, Reducer<Text, IntWritable, Text, IntWritable>.Context context) throws IOException, InterruptedException { int sum = 0; for (IntWritable obj : values) { sum += obj.get(); } result.set(sum); context.write(key, result); } } public static void main(String[] args) throws Exception { Configuration conf = new Configuration(); Job job = Job.getInstance(conf, "word count"); job.setJarByClass(Wordcount.class); job.setMapperClass(TokenizerMapper.class); job.setCombinerClass(IntSumReducer.class); job.setReducerClass(IntSumReducer.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(IntWritable.class); FileInputFormat.addInputPath(job, new Path("hdfs://master:9000/user/hduser/demo/test.txt")); FileOutputFormat.setOutputPath(job, new Path("hdfs://master:9000/user/hduser/demo/wordcount")); //FileInputFormat.addInputPath(job, new Path(args[0])); //FileOutputFormat.setOutputPath(job, new Path(args[1])); System.exit(job.waitForCompletion(true) ? 0 : 1); } } ``` 启动hadoop后,在eclipse中直接运行上面的程序,运行成功,生成了wordcount文件夹,里面有_SUCCESS文件,也有统计的结果文件 然后我想把程序打包成jar文件来运行,先把上面程序中的: ``` FileInputFormat.addInputPath(job, new Path("hdfs://master:9000/user/hduser/demo/test.txt")); FileOutputFormat.setOutputPath(job, new Path("hdfs://master:9000/user/hduser/demo/wordcount")); ``` 改成如下: ``` FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); ``` 就是通过终端输入这两个参数 用eclipse的export打包成jar文件,后在终端输入: ``` hadoop jar wordcount.jar wordcount.Wordcount hdfs://master:9000/user/hduser/demo/test.txt hdfs://master:9000/user/hduser/demo/wordcount ``` 运行就报错了,报错情况如下: ``` 17/09/09 11:18:53 INFO client.RMProxy: Connecting to ResourceManager at master/192.168.56.100:8050 17/09/09 11:18:54 WARN mapreduce.JobResourceUploader: Hadoop command-line option parsing not performed.

Hadoop测试任务wordcount失败
今天采用VMware和Ubuntu搭建了完全分布式环境,一台master 两台slave,hadoop是用的2.5.2. master和slave上的进程都能跑起来。可以通过hadoop fs进行文件块的上传和下载。 我想试一下wordcount的任务,但是任务提交后可以下发到slave上创建任务去执行,但是中间不知道出现什么错误,slave上的ssh会闪断一次,并且该台slave上面的datanode和nodeManager会被杀掉。换一台slave会出现同样的问题。查看日志,没有明显错误,只是显示收到 ``` 2016-10-31 15:28:42,236 ERROR org.apache.hadoop.yarn.server.nodemanager.NodeManager: RECEIVED SIGNAL 15: SIGTERM ``` 求大神指点,这是啥原因!!!! 日志路径:[http://pan.baidu.com/s/1eS0sRui](http://pan.baidu.com/s/1eS0sRui "日志地址")
hadoop中wordcount使用IKsegmenter分词器后本地编译运行通过,打成jar包后报IKsegmenter类无法找到
在本地编译可以正常运行,output中输出没有问题。 但打成jar之后想要在hadoop上运行就会报ClassNotFind异常,eclipse的export选项里面各种选项来回试了半天也没找到解决的办法,希望有大神指导一下。

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
