Review Comment:
The lock is moved to the failoverMasterWithLock method of FailoverService.
```java
private void failoverMasterWithLock(String masterHost) {
String failoverPath = getFailoverLockPath(NodeType.MASTER,
masterHost);
try {
registryClient.getLock(failoverPath);
this.failoverMaster(masterHost);
} catch (Exception e) {
LOGGER.error("{} server failover failed, host:{}",
NodeType.MASTER, masterHost, e);
} finally {
registryClient.releaseLock(failoverPath);
}
}
```
