5 years ago Hello,
You need to install scala and make sure that its bin directory on you PATH:
I am assuming that SCALA_HOME is the place you will install scala.
I am using scala-2.11.8.
export PATH=$SCALA_HOME/bin:$JAVA_HOME/bin:$ANT_HOME/bin:$HADOOP_HOME/bin:$PATH
Hope this helps,
best regards, Mahmoud Parsian
