> 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".
