Zhijie Shen commented on YARN-3984:
-----------------------------------

bq. If the info map is not empty, this record would be redundant and will take up storage
space.

Make sense. The patch looks good to me. Will commit it.

> Currently, the event column key is event_id?info_key?timestamp, which is not so friendly
to fetching all the events of an entity and sorting them in a chronologic order. IMHO, timestamp?event_id?info_key
may be a better key schema. I open this jira to continue the discussion about it which was
commented on YARN-3908.
