當本人在執行，Hadoop叢集自帶的wordcount例項的時候，報錯內容為輸入路徑不存在，在網上找了很久沒有解決，最後發現是因為我建立的log.1是在本地建立的，並沒有上傳到hdfs叢集中，所以在執行的時候會報錯，解決的辦法是：執行命令：

[root@master ~]# hadoop fs -put log.1 / #（將log.1檔案上傳到/目錄下）

操作之後可以再次執行命令：

[root@master ~]# hadoop jar /export/servers/hadoop/hadoop-2.7.3/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.3.jar wordcount /1.log /result

執行結果如下：
