----------------------------------
Summary: correct the annotation/comment about the frequency of
leader's ping
Key: ZOOKEEPER-4036
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4036
Project: ZooKeeper
Issue Type: Improvement
Reporter: maoling
{code:java}
// We ping twice a tick, so we only update the tick every other
// iteration
boolean tickSkip = true;
// If not null then shutdown this leader
String shutdownMessage = null;
{code}
>From the code, we can find it's a factual mistake. We ping half of a tick
>time, not twice a tick. For example, the tickTime is 2000ms(default), we ping
>every 1 s.
{code:java}
long start = Time.currentElapsedTime();
long cur = start;
long end = start + self.tickTime / 2;
while (cur < end) {
wait(end - cur);
cur = Time.currentElapsedTime();
}
{code}
