Solutions

1. Launch the dynamometer ApplicationMaster with its required arguments (fsimage directory and related parameters); none were supplied.

When it happens

Trigger: The dynamometer ApplicationMaster is launched by YARN without the required command-line arguments (e.g. NameNode RPC address or user), usually because the Client failed to pass them or the container was started manually.

Common situations: See trigger scenarios.
