Connect with eclipse HDFS but reported Error: failure to login Bug

I try to connect with eclipse HDFS but reported Error: failure to login error
Here is the online method :
---------------------------------------------- -------------------------------------------------- ------------
will HADOOP_HOME / lib directory commons-configuration-1.6.jar, commonshttpclient-
3.0.1.jar, commons-lang-2.4.jar, jackson-core-asl-1.0.1.jar and jackson-mapper-asl-1.0.1.jar ; etc. 5 pack
Copy to hadoop-eclipse-plugin-0.20.203.0.jar lib directory , and then modify the package META-INF directory of MANIFEST.MF, will modify the classpath about the content:
Bundle-ClassPath: classes /, lib / hadoop-core.jar, lib/commons-cli-1.2.jar, lib/commons-httpclient-
3.0.1.jar, lib/jackson-core-asl-1.0.1.jar, lib/jackson-mapper-asl-1.0.1.jar, lib/commons-configuration-
1.6.jar, lib/commons-lang-2.4.jar
