Dry Goods-Install eclipse-hadoop-plugin plug-in and HDFs API programming two important errors encountered in the solution

On the Windows Eclipse write HDFs API program, will encounter two errors, in the online search a lot of information, there is no solution, after a lot of time research, finally solved the problem

The error is 1.java.io.ioexception:hadoop_home or Hadoop.home.dir is not set.

2.java.io.ioexception:could not locate executable D:\hadoop-2.6.4\hadoop-2.6.4\bin/winutils.exe in the Hadoop bin Aries.

See no, reported a mistake, is not a lot of people have met, see the following solution

Add%hadoop_home%\bin;%hadoop_home%\sbin to Path; (Note that everyone's decompression path is different, do not do exactly as I do, unless your decompression path and I, my decompression to the D drive)

Restart Eclipse, and then test, notice, again reported a mistake, is not very strange, because a little something, the specific look at the picture

Nothing to add, see the jar package decompression after adding to the extracted file bin directory can be

After you restart Eclipse, run, test

Finally succeeded!!!
