             Summary: Add --checkpoint option to kafka-metadata-shell and 
deprecate --snapshot
                 Key: KAFKA-20668
                 URL: https://issues.apache.org/jira/browse/KAFKA-20668
             Project: Kafka
          Issue Type: Improvement
            Reporter: tony tang


The kafka-metadata-shell tool exposes a option --snapshot to point at the file 
to read. The flag name is misleading: the metadata snapshot use the .checkpoint 
suffix, while kafka also has .snapshot files in every log directory which are 
producer snapshots. This leads users to pass the wrong file.

Propose adding a --checkpoint option and deprecating --snapshot (keeping it as 
an alias for backward compatibility, with removal targeted for 5.0).
