Error in launching Spark REPL

I got pre-built Spark 1.4.1 and I'm running HDP 2.6. when I try to run spark-shell it gives me an error message as follows.

 Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataInputStream

ClassNotFoundException occurs when class loader could not find the required class in class path . So , basically you should check your class path and add the class in the classpath.

Check whether hadoop-common-0.21.0.jar is added to your classpath.

Is it possible that your Hadoop home is not set, as in here?

Cannot find hadoop installation: $HADOOP_HOME must be set or hadoop must be in the path
