hadoop-common-2.2.0-bin 32位

包含windows使用epclipse插件端开发Hadoop2.2.0需要的winutils.exe，hadoop.dll等等， 温馨提示hadoop.dll需要放在System32下哟，需要配置环境变量HADOOP_HOME为hadoop2.2.0在windows下解压的路径,以及在path下添加%HADOOP_HOME%/bin，对了记得重启电脑，然后你发现如下异常没了 Exception in thread "main" java.lang.NullPointerException at java.lang.ProcessBuilder.start(ProcessBuilder.java:441) at org.apache.hadoop.util.Shell.runCommand(Shell.java:445) at org.apache.hadoop.util.Shell.run(Shell.java:418) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:650) at org.apache.hadoop.util.Shell.execCommand(Shell.java:739) at org.apache.hadoop.util.Shell.execCommand(Shell.java:722) at org.apache.hadoop.fs.RawLocalFileSystem.setPermission(RawLocalFileSystem.java:633) at org.apache.hadoop.fs.RawLocalFileSystem.mkdirs(RawLocalFileSystem.java:421) at org.apache.hadoop.fs.FilterFileSystem.mkdirs(FilterFileSystem.java:281) at org.apache.hadoop.mapreduce.JobSubmissionFiles.getStagingDir(JobSubmissionFiles.java:125) at org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:348) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1285) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1282) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1548) at org.apache.hadoop.mapreduce.Job.submit(Job.java:1282) at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1303) at WordCount.main(WordCount.java:89)
