Ajith S commented on YARN-2398:
-------------------------------
I encountered with same scenario. I guess the bug is because of
{{org.apache.hadoop.yarn.client.ProtocolHATestBase.MiniYARNClusterForHATesting.waittingForFailOver()}}
{code}
private boolean waittingForFailOver() {
int maximumWaittingTime = 50;
int count = 0;
while (!failoverTriggered.get() && count >= maximumWaittingTime) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
// DO NOTHING
}
count++;
}
.......
{code}
here it should be {{count <= maximumWaittingTime}}
As otherwise, the while loop will be exit at first check itself, and there is
no actual wait hence it causes racecondition between failover and registerNM
