Importtsv command does not work in Hbase1.0.1.1

Question

I am trying to import a tsv file into my hbase table. I am using the following command:

hadoop jar /usr/local/hbase-1.0.1.1/lib/hbase-it-1.0.1.1.jar importtsv -Dimporttsv.columns=HBASE_ROW_KEY,a,b '-Dtable_name.separator=\t' table-name /path-to-input-file

It gives me the following error:

Exception in thread "main" java.lang.ClassNotFoundException: importtsv
        at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
        at java.net.URLClassLoader$1.run(URLClassLoader.java:355)

Have added guava jar in Hadoop classpath. Below is my bashrc file.

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export HADOOP_HOME=/usr/local/hadoop-2.6.0
export HBASE_HOME=/usr/local/hbase-1.0.1.1

export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
export PATH=$JAVA_HOME/bin:$PATH
export PATH=$PATH:/usr/local/hadoop-2.6.0/bin
export HADOOP_CLASSPATH=$JAVA_HOME/lib/tools.jar
export HADOOP_CLASSPATH=$HBASE_HOME/bin
export HADOOP_CLASSPATH=$HBASE_HOME/lib/guava-12.0.1.jar

export HBASE_CONF_DIR=$HBASE_HOME/conf
export HBASE_CLASS_PATH=$HBASE_CONF_DIR
export PATH=$HBASE_HOME/bin:$PATH

Any help is appreciated. Thanks in advance.

PS: Hadoop version - 2.6.0, Hbase version-1.0.1.1
