private final JournaledEditsCache cache;

When formatting the journal node, not clearing the cache value. 

void format(NamespaceInfo nsInfo, boolean force) throws IOException {
    Preconditions.checkState(nsInfo.getNamespaceID() != 0,
        "can't format with uninitialized namespace info: %s",
        nsInfo);
    LOG.info("Formatting journal id : " + journalId + " with namespace info: " +
        nsInfo + " and force: " + force);
    storage.format(nsInfo, force);
    refreshCachedData();
  }
