当MapReduce任务出现异常，无法正常执行时，可通过hadoop命令进行任务的终止操作。首先使用'hadoop job -list'查看当前运行的所有job，找到目标job的编号后，执行'hadoop job -kill [job编号]'即可终止指定的MapReduce任务。

当MapReduce任务不能正常执行时，我们可以将该任务kill掉。
使用 hadoop job -list 列出当前hadoop正在执行的jobs。
可以查看到job任务的编号，然后使用命令：
hadoop job -kill job编号 来杀死该job任务。

1.hadoop job -kill $JobId 2.mapred job -kill $JobId 这两个方式一致，如果无法杀死(卡死) 3.yarn application -kill $ApplicationId 可解

failed task可理解为自杀，也就是task本身出了问题而自杀；killed task可理解为是他杀，也就是jobtracker认为这个任务的执行是多余的，所以把任务直接杀掉。failed task再次调度时不会在那些曾经失败的节点上运行，而killed task则可能被再次调度到任何一个节点上（包括曾经失败多的节点）.起初用hadoop的时候经常在一个complete的job中看到...

${HADOOP_HOME}/bin/hadoop job -kill job_id hadoop的job在运行的过程中reduce 100%并不代表job全部做完，可以查看reduce输出判断是否全部做完，然后再去需要的数据 查看地址 http://ip:50030/jobtracker.jsp

前言在使用hadoop集群的时候,所有的任务都是最终以Application的形式跑在集群中,不管你是自己写的MR程序亦或是你写的hive sql转化成的mr任务,最终都是以Application应用的身份在跑.这些Application跑完之后,这些信息在jobHistory中就可以看了,可以说hadoop在这方面做得真的非常完整.但是完善归完善.但是jobHistory可以说是一种"事后分析"

### Hadoop Framework Jobs Explanation and Usage In the context of Hadoop, a job refers to an execution unit that processes data using MapReduce or other processing frameworks like Apache Spark. The configuration files mentioned such as `mapred-site.xml` play crucial roles in setting up how these jobs are executed within the cluster environment[^1]. For configuring mapreduce jobs specifically, one must ensure properties related to framework name point towards YARN which manages resources across distributed applications: ```xml <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> ``` This snippet ensures all mapreduce tasks will be managed by YARN resource manager. When submitting jobs from client machines configured similarly with correct `/etc/hosts`, it allows seamless interaction between nodes involved during computation phases including master node responsible for coordination alongside worker nodes performing actual computations on chunks of input datasets provided through HDFS (Hadoop Distributed File System)[^2]. The submission process typically involves specifying necessary parameters either via command line arguments when invoking jar files containing user-defined logic written against APIs exposed by chosen programming model over Hadoop ecosystem or programmatically inside scripts automating batch operations regularly scheduled throughout day-to-day analytics pipelines. To illustrate this concept practically consider following Python code utilizing PySpark API interacting directly with underlying infrastructure abstracted away under higher level constructs yet still leveraging core functionalities offered natively out-of-the-box without much hassle once setup correctly according previous sections regarding configurations adjustments made earlier steps described above. ```python from pyspark import SparkContext sc = SparkContext(appName="WordCount") lines = sc.textFile("hdfs://master:9000/user/data/input.txt") counts = lines.flatMap(lambda line: line.split()) \ .map(lambda word: (word, 1)) \ .reduceByKey(lambda a, b: a + b) output = counts.collect() for (word, count) in output: print(f"{word}: {count}") sc.stop() ``` --related questions-- 1. How does modifying `mapred-site.xml` affect job scheduling? 2. What role do workers play in executing Hadoop jobs? 3. Can you explain the significance of adjusting settings in `hadoop-env.sh` concerning Java options? 4. In what ways can Sqoop's installation impact Hadoop job performance? 5. Why is proper keytab file management critical for secure job submissions?
