Description
Sometimes, our service stuck because of some lock held by other thread, but we can get nothing from "stacks" for ReadWriteLock, and it is widely used in our services, like the fslock, cplock, dirlock of namenode.
Luckily, we can get thread parker from Thread object, it can help us see the thread parker clearly.
