> When calling the DFSZKFailoverController#create() method, call
> NameNode#initializeGenericKeys() twice.
> First call:
> DFSZKFailoverController#create() {
> ...
> NameNode.initializeGenericKeys(localNNConf, nsId, nnId);
> ...
> }
> The second call:
> NNHAServiceTarget construction method:
> NNHAServiceTarget() {
> ...
> NameNode.initializeGenericKeys(targetConf, nsId, nnId);
> ...
> }
> In fact, the parameters passed in the two calls are the same. Here you can
> remove the first call without affecting the program itself.
