Ability to initialize Spark-Shell with command script
This script allows a user to define a script file with code that will be
executed when then spark-shell starts up.
This initialization script file can be set either by setting the
SPARK_SHELL_RC environmental variable to the path, or by placing a file at
$HOME/.spark_shell_rc (the environmental variable takes precedence over the
home directory file)
There are two main usage scenarios:
1) The user has a set of commands they want run automatically whenever they
open spark-shell
2) Other software packages that depend on spark, and want to provide easy
access to their code in a way similar to spark-shell, can provide a wrapper
shell for spark-shell that adds the tool jars with ADD_JARS and then executes
an initialization with SPARK_SHELL_RC to do all the import calls and variable
initialization.
