[jira] [Updated] (KAFKA-20668) Add --checkpoint option to kafka-metadata-shell and deprecate --snapshot

     [ https://issues.apache.org/jira/browse/KAFKA-20668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

tony tang updated KAFKA-20668:
------------------------------
    Description: 
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).
