Solutions

1. Choose only one action: run the SecondaryNameNode with either -checkpoint or -geteditsize, not both.

When it happens

Trigger: The SecondaryNameNode command line includes mutually exclusive options.

Common situations: Running 'hdfs secondarynamenode -checkpoint -geteditsize' together.
