> I just saw the below piece of code in Fsnamesystem ctor.
> {code}
> writeLock();
> try {
> this.cacheManager = new CacheManager(this, conf, blockManager);
> } finally {
> writeUnlock();
> }
> {code}
> It seems unnecessary to keep writeLock here. I am not sure if there is a
> clear reason to keep the lock.
