How to get the help or explanation for the functions in Spark
shell?
Hi All,
I am new to Spark.
In the Spark shell, how can I get the help or explanation for those
functions that I can use for a variable or RDD? For example, after I input a
RDD's name with a dot (.) at the end, if I press the Tab key, a list of
functions that I can use for this RDD will be displayed, but I dont know how
to use these functions.
Your help is greatly appreciated.

In PySpark you can also do help(my_rdd) and get a nice help page of methods
available.

You can consult the docs at :
https://spark.apache.org/docs/latest/api/scala/index.html#package
In particular, the rdd docs contain the explanation of each method :
https://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.rdd.RDD
