Aaron Lindsey commented on GEODE-8200:
--------------------------------------

The only difference is that now it's happening for restore redundancy instead 
of rebalance, but it's pretty much the same scenario where we see the issue. 
(We switched to using restore redundancy instead of rebalance after that 
operation was added to Geode.)

> Rebalance operations stuck in "IN_PROGRESS" state forever

> We use the management REST API to call rebalance immediately before stopping 
> a server to limit the possibility of data loss. In a cluster with 3 locators, 
> 3 servers, and no regions, we noticed that sometimes the rebalance operation 
> never ends if one of the locators is restarting concurrently with the 
> rebalance operation.
> More specifically, the scenario where we see this issue crop up is during an 
> automated "rolling restart" operation in a Kubernetes environment which 
> proceeds as follows:
> * At most one locator and one server are restarting at any point in time
> * Each locator/server waits until the previous locator/server is fully online 
> before restarting
> * Immediately before stopping a server, a rebalance operation is performed 
> and the server is not stopped until the rebalance operation is completed
> The impact of this issue is that the "rolling restart" operation will never 
> complete, because it cannot proceed with stopping a server until the 
> rebalance operation is completed. A human is then required to intervene and 
> manually trigger a rebalance and stop the server. This type of "rolling 
> restart" operation is triggered fairly often in Kubernetes — any time part of 
> the configuration of the locators or servers changes. 
> The following JSON is a sample response from the management REST API that 
> shows the rebalance operation stuck in "IN_PROGRESS".
