Till Rohrmann created FLINK-3560:
------------------------------------
Summary: Examples shouldn't always print usage statement
Key: FLINK-3560
URL: https://issues.apache.org/jira/browse/FLINK-3560
Project: Flink
Issue Type: Improvement
Components: Examples
Affects Versions: 1.0.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Priority: Minor
At the moment all our examples print a usage statement no matter whether the
parameters have been provided or not. This can be confusing for people because
an usage statement is usually only printed if one has specified a wrong
parameter or if a parameter is missing.
I propose to remove the unchecked printing of the usage statement.
