Hadoop2中的hadoop-test.jar在哪里？ [英] where is hadoop-test.jar in Hadoop2?

问题描述

我想用 testmapredsort 进行Hadoop中的基准测试排序。我现在不使用TeraSort。
$ b

hadoop- * test * .jar 应该包含 testmapredsort class。但是在 Hadoop2 中没有看到 hadoop- * test * .jar 。

  hadoop jar hadoop / share / hadoop / common / hadoop-common-2.2.0-tests.jar testmapredsort / data / unsorted -data -sortOutput / data / sorted-data 
  

解决方案

Hadoop 1， testmapredsort 是从 AllTestDriver.java 启动的， Hadoop的测试1.2.1.jar 。在Hadoop 2中，它现在位于MapredTestDriver.java中，它可以在 hadoop / share / hadoop / mapreduce / hadoop-mapreduce-client-jobclient-2.2.0-tests.jar中找到
$ p $ hadoop jar hadoop / share / hadoop / mapreduce / hadoop-mapreduce-client-jobclient-2.2.0-tests .jar testmapredsort -sortInput / data / unsorted-data -sortOutput / data / sorted-data





I want to use testmapredsort for benchmarking sort in Hadoop. I am NOT using TeraSort now.

hadoop-*test*.jar is supposed to contain the testmapredsort class. But I do not see hadoop-*test*.jar in Hadoop2.

hadoop jar hadoop/share/hadoop/common/hadoop-common-2.2.0-tests.jar testmapredsort /data/unsorted-data -sortOutput /data/sorted-data

解决方案

In Hadoop 1, testmapredsort is launched from AllTestDriver.java, which was indeed in e.g. hadoop-test-1.2.1.jar. In Hadoop 2, it's now in MapredTestDriver.java, which can be found inside of hadoop/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-2.2.0-tests.jar

hadoop jar hadoop/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-2.2.0-tests.jar testmapredsort -sortInput /data/unsorted-data -sortOutput /data/sorted-data
