JIRA: [HDFS-16402](https://issues.apache.org/jira/browse/HDFS-16402). After reconfig `dfs.datanode.data.dir`, we found that the stats of the Namenode Web became negative and there were many NPE in namenode logs. This problem has been solved by [HDFS-14042](https://issues.apache.org/jira/browse/HDFS-14042). However, if `HeartbeatManager#updateHeartbeat` and `HeartbeatManager#updateLifeline` throw other exceptions, stats errors can also occur. We should ensure that `stats.subtract()` and `stats.add()` are transactional. -- This is an automated message from the Apache Git Service.
