Initial build: 5.5.4-4338
MH Build: 6.5.0-3939
- Initiate 3 node cluster (2 nodes only KV & 3rd node with index,query) using build 5.5.4-4338
- Create Couchbase bucket with replica=1
- Upgrade only the KV nodes to MH build (6.5.0-4947)
- Try sync_write to the already created bucket
Sync_write fails with reason com.couchbase.client.core.error.FeatureNotAvailableException.
Since durability depends only on KV nodes, syncWrite should succeed with all KV nodes are upgraded to MH build.
Note: Behavior is same even while using latest MH builds.
