[Doc'd] Couchbase UI shows a node down when Rest API is used to rename a node in a multiple node cluster

When we reference a node from hostname to IP in a multiple node cluster, using REST API, then UI of another node shows that first node is down.

In Detail:

Steps followed:

1. Take a 2-node cluster referred with hostame (lets say node A and node B).
2. Rename node A from hostname to its corresponding IP, using the rest API - node/controller/rename.

Result: Node A gets renamed to its corresponding IP but the UI of other node(i.e. node B) shows that node A is down.

Attaching cbcollectinfo from both the nodes. Also uploading the screen-shot of UI. Please see.
