I have setup the 'hadoop' by following the instructions given in here.
I downloaded and deployed it successfully and can able to run all the daemons except historyserver and run the example programs.
when I run sbin/yarn-daemon.sh start historyserver, the following error is displayed.
Exception in thread "main" java.lang.NoClassDefFoundError: historyserver
Caused by: java.lang.ClassNotFoundException: historyserver

Can anyone do help me in this issue?
To start the history server, it seems that the command is now:
./sbin/mr-jobhistory-daemon.sh start historyserver

I have configured and install the HADOOP
I configured from the website http://www.srccodes.com/p/article/38/build-install-configure-run-apache-hadoop-2.2.0-microsoft-windows-os
when I format the hadoop namenode using the command
alim#Hadoop~/hadoop-2.4.0/bin$ ./hdfs namenode -format or alim#Hadoop~/hadoop-2.4.0/bin$ ./hadoop namenode -format
It is showing the "NoClassDefFoundError" exception
The following is the exception shown when I ran the "hadoop namenode -format" command
java.lang.NoClassDefFoundError: org/apache/hadoop/hdfs/server/namenode/NameNode

At first i thought the hadoop classpath is the not pointing to the Hadoop-core jar files but when I ran the command alim#Hadoop~/hadoop-2.4.0/bin$ ./hadoop classpath It is showing the correct path to libraries then why the NoClassDefFoundError is gettingThe path to libraries are showing like below:
/home/alim/hadoop-2.4.0/etc/hadoop:/home/alim/hadoop-2.4.0/share/hadoop/common/lib/:/home/alim/hadoop-2.4.0/share/hadoop/common/:/home/alim/hadoop-2.4.0/share/hadoop/hdfs:/home/alim/hadoop-2.4.0/share/hadoop/hdfs/lib/:/home/alim/hadoop-2.4.0/share/hadoop/hdfs/:/home/alim/hadoop-2.4.0/share/hadoop/yarn/lib/:/home/alim/hadoop-2.4.0/share/hadoop/yarn/:/home/alim/hadoop-2.4.0/share/hadoop/mapreduce/lib/:/home/alim/hadoop-2.4.0/share/hadoop/mapreduce/:C:\cygwin64\home\alim\hadoop-2.4.0/contrib/capacity-scheduler/*.jar

Any ideas on how to resolve this issue?
The � shows that it may be a character, which looks like hyphen '-' . Please inspect this.
Also, whenever you are using -D option, its best practice to use a complete jar name (rather than wild card). This will make sure that you are missing nothing.

I have already added the following Jar file to my project:--
Oracle.bpm.runtime.jar
Oracle.bpm.client.jar
Bpm-services.jar
Wsclient.jar
But still the issue is not resolved..
Any Suggestion??????
Aside from the reason it is not working you should be using the TaskQueryService provided by Oracle out of the box.

BUILD SUCCESSFUL (total time: 2 seconds)
In your project properties (right click on your project and select properties). Select under categories Run. Check the setting for your main class. I expect it is still set to qkd.QKDApp enter the class name of your new main class.
