Stephan Ewen commented on FLINK-2459:
-------------------------------------
How about reworking the test as a whole? Right now, it starts an entire
cluster, just to validate that a flag is passed from the command line interface
to the Client class. This can be tested in a Unit test style, by just
instantiating the CLI with a mock client and validating that the flag is
properly passed.
The problem is that we cannot add these "start a cluster" tests for every
configuration flag. Starting a local cluster takes a bit (Akka initialization
is fairly slow) and the sum of these tests already blows up the build times.

> A recent commit (authored by me) added a flag on CliFrontend to disable
> sysout logging on console. The unit test for this fails sporadically because
> of unavailable port while starting the cluster.
