Subject [jira] [Updated] (HDDS-490) Improve om and scm start up options
Date Wed, 10 Oct 2018 19:43:00 GMT

     [ https://issues.apache.org/jira/browse/HDDS-490?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal updated HDDS-490:
-------------------------------
    Description: 
I propose the following changes:
 # Rename _createObjectStore_ to _init_
 # Use double-dash for all long options (Unix convention)
 # Fail to format existing object store. If a user runs:
{code:java}
ozone om --init{code}
And OM is already initialized, it should give a warning message and exit the process with
success.

  was:
I propose the following changes:
 # Rename createObjectStore to format
 # Change the flag to use --createObjectStore instead of using -createObjectStore. It is
also applicable to other scm and om startup options.
 # Fail to format existing object store. If a user runs:
{code:java}
ozone om -createObjectStore{code}
And there is already an object store, it should give a warning message and exit the process.
