Hi- I attempted to upgrade our ~40 node (Community) from 5.1 to 5.2 and evolve to using YARN. I added a node running Resource Manager, and another with History Manager. I thought I followed the instructions, but now have a dead cluster with the CLDB in this error state:
INFO CLDBServer [Lookup-5]: Rejecting RPC 2345.5 from 192.168.4.20:46642 with status 3 as the minimum replication count of CLDB volume is not met. Waiting for additional nodes to come online.
I tried moving the CLDB to two of the other nodes that were CLDB replicas, with the same basic result.
Is there any way I can tell the CLDB to use the copy that it has and proceed? It seems that it's waiting for the other nodes to come on-line, which they cannot do since they have no CLDB?
