Locate Scala installation for Spark

Question

I'm using EMR and can launch spark-shell, but I want to run Scala REPL. Currently when I type scala command on shell it says:

-bash: scala: command not found

How to locate and run Scala REPL give that Spark is already installed and configured?

Answer 1

As already told by @ernest_k, EMR doesn't come with Scala installation.

With that said, I used the steps mentioned in this blog to install Scala on EMR

# perform customary yum update
sudo yum update

# download Scala installer RPM
wget https://downloads.lightbend.com/scala/2.13.0-M5/scala-2.13.0-M5.rpm

# install Scala RPM
sudo yum install scala-2.12.5.rpm
