ConfX updated HADOOP-18905:
---------------------------
    Description: 
Graceful fence timeout of FailoverController in ZKFailovercontroller equals to 
`ha.failover-controller.graceful-fence.rpc-timeout.ms` * 2. Since users are 
unaware of this calculation, it thus has risks of overflowing to a negative 
number if users set `ha.failover-controller.graceful-fence.rpc-timeout.ms` to a 
large value.
 
To reproduce:
1. set `ha.failover-controller.graceful-fence.rpc-timeout.ms` to 1092752431
2. run `mvn surefire:test 
-Dtest=org.apache.hadoop.ha.TestZKFailoverController#testGracefulFailoverFailBecomingStandby`
 
We create a PR that provides a fix by checking the timeout after multiplication 
is at least 0.
