SPARK-1192: The document for most of the parameters used in core component
I grep the code in core component, I found that around 30 parameters in the
implementation is actually used but undocumented. By reading the source code, I
found that some of them are actually very useful for the user.
I suggest to make a complete document on the parameters.
Also some parameters are having confusing names
1. spark.shuffle.copier.threads - this parameters is to control how many
threads you will use when you start a Netty-based shuffle service....but from
the name, we cannot get this information
2. spark.shuffle.sender.port - the similar problem with the above one, when
you use Netty-based shuffle receiver, you will have to setup a Netty-based
sender...this parameter is to setup the port used by the Netty sender, but the
name cannot convey this information.
---
To facilitate the review, I mostly make a commit for each parameter, but
some highly related parameters are combined together. The format of the commit
title is like
" %s - %s L%d" % parameter name, File/Class name, line-number
