From the perspective of fallback, it's better to make `flushAsync` method private in `HBaseAdmin`, but I introduce this method in `Admin` interface based on the following consideration a. it is not a good practice to call asynchronous functions in a synchronous api b. it still works if the master supports and enables `FlushTablePRocedure` c. if an unsupported exception is thrown, the user can perceive it and handle it in the upper layer, just like a normal `IOException`. > > XXXAsync methods are common in the Admin interface so we should provide it. > > And how could our users handle the unsupported exception in upper layer? We do not expose the legacyFlush method to them, they can only retry on the same method and then get the same exception again? Our user can fallback to the old flush implementation by calling **flush** method. If our users really need asynchronous calls, maybe we can suggest them to consider **AsyncHBaseAdmin#flush** API in the doc. Do you think it is necessary for us to implement fallback logic in the **HBaseAdmin#flushAsync** method? -- This is an automated message from the Apache Git Service.
