Description
This was detected while automated test was running.
Test looks for rebalance complete after adding a node, through REST API then make a REST API call to the newly added server port 8091.
However, rest API was not responding or returns 500 for couple of seconds.
This ticket is more like a question whether rebalance complete guarantee REST API is ready for the newly added node.
If yes, I will add retrial logic on automation suppressing REST API exceptions for couple of times.
