Review comment:
yeah, I saw the `UnsupportedOperationException` and the timeout in the
unit test logs, then the master didn't stop, such that I added a section in
HMaster to catch this exception. Did I do it wrong ? or any idea how I can fail
the procedure?
```
initMetaProc.await();
if (initMetaProc.isFailed() && initMetaProc.hasException()) {
throw new IOException("Failed to initialize meta table",
initMetaProc.getException());
}
```
