Sangjin Lee commented on YARN-3908:
-----------------------------------
Sorry my bad. I mistakenly pulled up the v.1 of {{TimelineEvent}}. Our version
uses only the id and the timestamp for equality:
{code:title=TimelineEvent.java|borderStyle=solid}
@Override
public int hashCode() {
int result = (int) (timestamp ^ (timestamp >>> 32));
result = 31 * result + id.hashCode();
return result;
}
@Override
public boolean equals(Object o) {
if (this == o)
return true;
if (!(o instanceof TimelineEvent))
return false;
TimelineEvent event = (TimelineEvent) o;
if (timestamp != event.timestamp)
return false;
if (!id.equals(event.id)) {
return false;
}
return true;
}
@Override
public int compareTo(TimelineEvent other) {
if (timestamp > other.timestamp) {
return -1;
} else if (timestamp < other.timestamp) {
return 1;
} else {
return id.compareTo(other.id);
}
}
{code}
So that answers my first question. Sorry for the confusion! Only the second
question remains...

> 1. In HBaseTimelineWriterImpl, the info column family contains the basic
> fields of a timeline entity plus events. However, entity#info map is not
> stored at all.
> 2 event#timestamp is also not persisted.
