>          Components: Distributed Cache
>    Affects Versions: 4.1.0.Final, 4.2.0.ALPHA1
>            Reporter: Galder Zamarreño

> In the case of a MergeView, a node might be required to rejoin, meaning that it needs to rehash its keys. This can happen if the node is not in the winning partition.
> In this cases, rehash might fail because after the initial DistributionManagerImpl.joinComplete, because joinComplete is still set to true.
