> In the current implementation the clone call waits until after the newly created table isTableEnabled. However there is another state (apparently orthogonal) that a newly created table is assumed to be – isTableAvailable (all regions assigned). The logic for checking after table creation and after clone creation are slightly different – creation does the equivalent of isTableAvailable but clone does not check this availability condition.
> This causes flaky failures in tests that quickly try to use/delete a newly cloned table.
> TestRestoreSnapshotFromClient#testCloneSnapshot
> TestRestoreFlushSnapshotFromCleitn#testCloneSnapshot
> I believe there also are race conditions because of the postTableCreateHandler corpco and postTableDeleteHandler coproc hooks.
