Hi, I've just tried to add a new DC and new node to my cluster (3 DCs and 10 nodes) and the new node has a different schema version:
Cluster Information: Name: cluster Snitch: org.apache.cassandra.locator.DynamicEndpointSnitch Partitioner: org.apache.cassandra.dht.Murmur3Partitioner Schema versions: 7e12a13e-dcca-301b-a5ce-b1ad29fbbacb: [x.x.x.x, ..., ...] bb186922-82b5-3a61-9c12-bf4eb87b9155: [new.new.new.new] I've tried: - node decommission and node re-addition - resetlocalschema - rebuild - replace node - repair - cluster restart (node-by-node) The MigrationManager constantly running on the new node and try to migrate schema: DEBUG [NonPeriodicTasks:1] 2018-04-30 09:33:22,405 MigrationManager.java:125 - submitting migration task for /x.x.x.x What also can I do? :( Bye, Gábor Auth
