How to use write and run MapReduce in eclipse on windows.

(1) Configure hadoop-eclipse-plugin-1.0.3.jar

\\192.168.1.19\development\GroupM\Softwares\hadoop\hadoop-eclipse-plugin-1.0.3.jar

(2) copy all the jar file in the hadoop into your classpath.

(3) copy hbase\hbase-0.*.*.jar, hbase\lib\zookeeper-3.4.3.jar into your classpath.

(4) copy hbase-site.xml into your classpath.

(5) Modify org.apache.hadoop.fs.FileUtil.java

private static void checkReturnValue(boolean rv, File p,

FsPermission permission

) throws IOException {

/*if (!rv) {

throw new IOException("Failed to set permissions of path: " + p +

" to " +

String.format("%04o", permission.toShort()));

}*/
