George Jahad commented on HDDS-5328:
------------------------------------
I agree "unknown command type" is confusing. Based on the fact that PR #1845
was closed without merging, I don't think that the Delete Container commend
will ever exist, and the correct fix for this case is, as you said, to remove
that command. I will change this ticket/PR, to remove the command. Do you
agree? Is there someone else I should ask?
In addition, if we do decide to leave it in the cli without adding it to the
server, I've found another problem.
I fixed the error message here:
https://github.com/GeorgeJahad/ozone/tree/HDDS-5328-fix-delete-container-error-message
But when I test it, it gets retried 300 times, (i think because of the hadoop
rpc retry mechanism). After the retries, it finally gets to my code to print
the error, but I doubt users will really wait that long. So if we don't want to
remove it, I think we may need to fix the retries as well.
