When configuring the MapReduce plugin, pop-up error org/apache/hadoop/eclipse/preferences/mapreducepreferencepage:unsupported Major.minor version 51.0 (Hadoop2.7.3 cluster deployment)

Reason:

Hadoop-eclipse-plugin-2.7.3.jar compiled JDK versions are inconsistent with the JDK version used by Eclipse startup.

Solution One :

Modify the Myeclipse.ini file to resolve it. D:/java/myeclipse/common/binary/com.sun.java.jdk.win32.x86_1.6.0.013/jre/bin/client/jvm.dll to: D:/Program Files ( x86)/java/jdk1.7.0_45/jre/bin/client/jvm.dlljdk1.7.0_45 version of the JDK for your own installation

If it is not valid, check that the Hadoop version set in the system environment variable hadoop_home is consistent with the plug-in version.

Solution Two:

Compile a Hadoop plugin yourself according to the operating manual.

Reference:Windows compiled Hadoop 2.x hadoop-eclipse-plugin plug-in (very detailed explanation, the subsequent installation of the plug-in part and the problem is very detailed, very nice one post)
