> To reproduce the issue: 
> {code:java}
> $ bin/hdfs dfsrouteradmin -safemode enter
> Successfully enter safe mode.
> $ bin/hdfs dfsrouteradmin -safemode get
> Safe Mode: true{code}
> And then, 
> {code:java}
> $ bin/hdfs dfsrouteradmin -safemode get
> Safe Mode: false{code}
> From the code, it looks like the periodicInvoke triggers the leave.
> {code:java}
> public void periodicInvoke() {
> ......
>   // Always update to indicate our cache was updated
>   if (isCacheStale) {
>     if (!rpcServer.isInSafeMode()) {

>   } else if (rpcServer.isInSafeMode()) {
