> Remove the redundant write lock in addBlockPool
> -----------------------------------------------

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Reporter: dingshun
> Priority: Major
> Labels: pull-request-available
>
> When patching the datanode's fine-grained lock, we found that the datanode
> couldn't start，maybe happened deadlock，when addBlockPool, so we can remove it.
