+This page contains a collection of best practices for Flink programmers on
how to solve frequently encountered problems.

+
+## Parsing command line arguments and passing them around in your Flink
application
+
+
+Almost all Flink applications, both batch and streaming rely on external
configuration parameters.
+For example for specifying input and output sources (like paths or
addresses), also system parameters (parallelism, runtime configuration) and
application specific parameters (often used within the user functions).
+
+Since version 0.9 we are providing a simple called `ParameterTool` to
provide at least some basic tooling for solving these problems.

> Hadoop users are used to setting job configuration through "-D" on the
> command line.
> Right now, Flink users have to manually parse command line arguments and pass
> them to the methods.
> It would be nice to provide a standard args parser with is taking care of
> such stuff.
