KV-Engine Mad-Hatter Beta
Description
This occurs on top-of-tree for mad-hatter. Here's the recipe:
- cluster_run two nodes
From GUI - create cluster
- add 2nd node
- rebalance
- create couchbase bucket
- create two documents in bucket
- failover node1 to node0
- create two more documents in bucket
- click delta recovery
- click rebalance
You'll get a pop up saying rebalance exited with reason mover_crashed (see screenshot attached). Abhijeeth Nuthan reproduced on his desktop with full recovery and he did a cursory look and found memcached throwing an exception.
