Hi,

We have recently encountered several schema disagreement issue while upgrading 
Cassandra. In one of the cases, the 2-node cluster idled for over 30 minutes 
and their schema remain unsynced. Due to other logic flows, Cassandra cannot be 
restarted, and hence we need to come up an alternative on-the-fly. We are 
thinking to do a nodetool resetlocalschema to force the schema synchronization. 
How safe is this method? Do we need to disable thrift/gossip protocol before 
performing this function, and enable them back after resync completes?

Thanks in advance!

Sincerely,

Michael Fong
