Java.io.IOException:Could not locate executable null\bin\winutils.exe in the Hadoop binaries.

1: This problem is all played rotten, here I also record, convenient after the brain repair:

I am testing hbase for this problem when creating a data table, in short, window operation Hadoop will encounter this problem:

1 The first step: Configure the window's environment variables yourself (obviously it should be a hadoop_home problem.) If Hadoop_home is empty, it must be fullexename to Null\bin\winutils.exe. The workaround is simple, configure the environment variable,). 2 The second step: do not want to restart the computer can be added in the program:3System.setproperty ("Hadoop.home.dir","c:\\users\\administrator\\desktop\\hadoop-2.7.3\\hadoop-2.7.3");4 For example I added here:5 @Before6      Public voidinit () throws Exception {7System.setproperty ("Hadoop.home.dir","e:\\hadoop-2.6.4");8         //Configuration9Config =hbaseconfiguration.create ();Ten         //Zookeeper Address OneConfig.Set("Hbase.zookeeper.quorum","Master,slaver1,slaver2"); A         //Zookeeper Port -Config.Set("Hbase.zookeeper.property.clientPort","2181"); -         //Create a connection with Factory mode theConnection =connectionfactory.createconnection (config); -         //getting table connections via connection -Table = connection.gettable (Tablename.valueof ("User")); - } +Step three: Go to https://Github.com/srccodes/hadoop-common-2.2.0-bin/tree/master/bin -Download winutils.exe file copy to your E:\hadoop-2.6.4\ Bin directory inside.  + Fourth Step: Re-run the program is OK, problem solving.
