Zhijie Shen commented on YARN-3046:
-----------------------------------
Task entity Id should be be the job Id, but the task Id.
PS: there's a typo here.
{code}
1074 // create TaskEntity from HitoryEvent with adding other info,
like:
1075 // jobId, timestamp, entityType and relatedJobEntity.
1076 private
org.apache.hadoop.yarn.api.records.timelineservice.TimelineEntity
1077 createTaskEntity(HistoryEvent event, long timestamp, JobId jobId,
1078 String entityType, String relatedJobEntity) {
1079 org.apache.hadoop.yarn.api.records.timelineservice.TimelineEntity
entity =
1080 createJobEntity(event, timestamp, jobId, entityType);
1081 entity.addIsRelatedToEntity(relatedJobEntity, jobId.toString());
1082 return entity;
