thank you for the help.
copy hadoop libs in extlib directory and prepare war then try it.
cp $HADOOP_HOME/share/hadoop/*/hadoop-*.jar./libext/
cp $HADOOP_HOME /share/hadoop/*/lib/*.jar./libext/
cp mysql-connector-java-5.1.29-bin.jarlibext/
bin/oozie-setup.sh prepare-war
run this after copy and prepare.
./bin/oozie-setup.sh sharelib create -fs hdfs://IP(HOSTNAME):9000

Place your third party JAR file on one of hadoop's default lib folder. For example, $HADOOP_HOME/share/hadoop/common/lib.
I am trying to add all the jar files in the directory below but I get
Exception in thread "main" java.lang.NoClassDefFoundError: twitter4j/TwitterException error.
I am sure there is TwitterException class inside the .jar file. Is there any error in my classpath syntax ?

I am using ubuntu and jdk 1.7. I tried the same command in windows and it works flawlessly. Is there anything special to do related to Ubuntu OS?
The * syntax for classpaths is rather limited. Try:
java -classpath "~/twitter4j-2.2.6/lib/*:." GetHashtag
