Josh Elser commented on HBASE-20705:
------------------------------------
{quote}In case of space quota (by default) this scenario is handled
{quote}
This was definitely something conscious we added because there isn't any reason
to keep around a (space) quota for a table you no longer need. My guess would
be that the similar convenience doesn't exit for RPC quotas. You could copy
this feature from space quotas if you want to build it for rpc quotas, or just
delete the rpc quota yourself if you want a quick cleanup.
> Having RPC Quota on a table prevents Space quota to be recreated/removed
