> Currently KeyManager#openKey makes an allocateBlock call without releasing
> the bucket lock. Since allocateBlock requires a rpc connection to SCM, the
> handler thread in OM would hold the bucket lock until rpc is complete. Since
> allocateBlock call does not require a bucket lock to be held, allocateBlock
> call can be made after releasing the bucket lock.
