Duplicated thread names exists in jstack sometimes, because StoreFileOpenerThreads are created per region and have same names. 

Suggest adding region name to corresponding thread name in order to distinguish StoreFileOpenerThreads, which are created per region. This could be helpful for troubleShooting.
