AsyncTableRegionLocator (Apache HBase 2.1.9 API)

All Known Implementing Classes:

AsyncTableRegionLocatorImpl
```
@InterfaceAudience.Public
public interface AsyncTableRegionLocator
```
The asynchronous version of RegionLocator.
Usually the implementations will not throw any exception directly, you need to get the exception from the returned CompletableFuture.

Since:

2.0.0
