> prepareToEnterState in HAState is called without the context being locked.
> But in NameNode#NameNode, prepareToEnterState is after haContext.writeLock()
>
> {code:java}
> try {
> haContext.writeLock();
> state.prepareToEnterState(haContext);
> state.enterState(haContext);
> } finally {
> haContext.writeUnlock();
> }
> {code}
>
> Is it OK?
