Sylvain Lebresne commented on CASSANDRA-4664:
---------------------------------------------
bq. I'm pretty sure we've never disallowed system keyspace writes intentionally
I don't know who exactly added that code but I would have opened a bug report
if it wasn't there. I really think allowing write in the system table in
general is really really bad idea. You can very easily mess us your node in
subtle way. And I couldn't swear there isn't ways to mess up a good part of
your cluster by writing something you should in the schema tables or in some
value propagated by gossip.
This is not saying no user interaction should ever translate to a write in the
system table, and I'm all for adding a jmx call to truncate hints (doesn't that
exist already?), but unrestricted writes feels like way to much power to give
by default.
