----------------------------------------
Summary: FLETest#testLE is flaky on windows boxes
Key: ZOOKEEPER-1733
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1733
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.4.5
Reporter: Jeffrey Zhong
Priority: Minor
FLETest#testLE fail intermittently on windows boxes. The reason is that in
LEThread#run() we have:
{code}
if(leader == i){
synchronized(finalObj){
successCount++;
if(successCount > (count/2))
finalObj.notify();
}
break;
}
{code}
Basically once we have a confirmed leader, the leader thread dies due to the
"break" of while loop.
While in the verification step, we check if the leader thread alive or not as
following:
{code}
if(threads.get((int) leader).isAlive()){
Assert.fail("Leader hasn't joined: " + leader);
}
{code}
On windows boxes, the above verification step fails frequently because leader
thread most likely already exits.
Do we know why we have the leader alive verification step only lead thread can
bump up successCount >= count/2?
