lucperkins opened a new pull request #1744: Remove usage() call on ParameterException URL: https://github.com/apache/incubator-pulsar/pull/1744 As it stands, the `pulsar-admin` tool (in particular the `functions` command) provides full usage output whenever a `ParameterException` is thrown. The issue is that the exception message is buried by the usage printout (which is inappropriate in this case anyway).
