Master must start with yarn,spark

I am getting this error when is want to run SparkPi example. 

   beyhan@beyhan:~/spark-1.2.0-bin-hadoop2.4$ /home/beyhan/spark-1.2.0-bin-hadoop2.4/bin/spark-submit --master ego-client --class org.apache.spark.examples.SparkPi /home/beyhan/spark-1.2.0-bin-hadoop2.4/lib/spark-examples-1.jar
        Spark assembly has been built with Hive, including Datanucleus jars on classpath
        Error: Master must start with yarn, spark, mesos, or local
        Run with --help for usage help or --verbose for debug output
        Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties

Also i already start my master via another terminal

>./sbin/start-master.sh 
starting org.apache.spark.deploy.master.Master, logging to /home/beyhan/spark-1.2.0-bin-hadoop2.4/sbin/../logs/spark-beyhan-org.apache.spark.deploy.master.Master-1-beyhan.out

Any suggestion ? Thanks.

Download and extract Spark:

$ cd ~/Downloads
$ wget -c http://archive.apache.org/dist/spark/spark-1.2.0/spark-1.2.0-bin-hadoop2.4.tgz
$ cd /tmp
$ tar zxf ~/Downloads/spark-1.2.0-bin-hadoop2.4.tgz
$ cd spark-1.2.0-bin-hadoop2.4/

Start master:

$ sbin/start-master.sh

Find master's URL from logs in the file that above command printed. Lets assume that master is: spark://ego-server:7077

In this case, you can also find your master url by visiting this URL: http://localhost:8080/

Start one slave, and connect it to master:

$ sbin/start-slave.sh --master spark://ego-server:7077

Another way to ensure that master up and running start a shell bound to that master:

$ bin/spark-submit --master "spark://ego-server:7077"

If you get a spark shell, then everything seems fine.

Now execute your job:

$ find . -name "spark-example*jar"
./lib/spark-examples-1.2.0-hadoop2.4.0.jar

$ bin/spark-submit --master "spark://ego-server:7077" --class org.apache.spark.examples.SparkPi ./lib/spark-examples-1.2.0-hadoop2.4.0.jar

The error you're getting

Error: Master must start with yarn, spark, mesos, or local

Means that --master ego-client is not recognized by spark.

Use 

--master local

for a local execution of spark or 

--master spark://your-spark-master-ip:7077
