> 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.
