This function looks for files with the "wrong" replica type in their name, and if it finds any, renames them. Those files may have ended up on this server either because: - 1. We restored them from another server, where they were named according to another replica type. Or, - 2. The {@link voldemort.store.readonly.mr.azkaban.VoldemortBuildAndPushJob} and the {@link voldemort.store.readonly.fetcher.HdfsFetcher} are operating in 'build.primary.replicas.only' mode, so they only ever built and fetched replica 0 of any given file. Note: This is an implementation detail of the READONLY_V2 naming scheme, and should not be used outside of that scope. @param masterPartitionId partition ID of the "primary replica" @param correctReplicaType replica number which should be found on the current node for the provided masterPartitionId.
