Anu Engineer commented on HDDS-429:
-----------------------------------
I am +1 on this patch. I am not sure if we can take a readlock() and promote it
to a writeLock() with a dead lock in Java. I think you can. But the
"{color:#000080}synchronized"{color} {color:#000080}works equally well. I will
commit this now. {color}

> Currently, {{StorageContainerManager}} uses {{ReentrantLock}} for
> synchronization. We can replace this with {{ReentrantReadWriteLock}} to get
> better performance.
