[GitHub] [pinot] Jackie-Jiang opened a new pull request, #10593: Check EV not exist before allowing creating the table

Jackie-Jiang opened a new pull request, #10593:
URL: https://github.com/apache/pinot/pull/10593

   In #8422 we introduced the table delete message to delete a table on the server, and server will wait for EV to disappear then cleaning up the table data manager. We should not allow re-creating the table before EV is deleted to ensure that logic doesn't break.

   What is the blocker for not implementing for OFFLINE tables?

Review Comment:
   The main concern is that this is behavior change, and out of the scope of this PR. We can address this separately if desired, but need to explicitly call out this behavior change. Thus left a TODO so that people aware of this

   I think we should mention this in the TODO as well, why it was not implemented?
