Joep Rottinghuis commented on YARN-3706:
----------------------------------------
I've noticed that in
o.a.h.y.s.t.s.EntityInfoColumnDetails.storeWithColumnPrefix we use
TimelineEntitySchemaConstants.ROW_KEY_SEPARATOR to separate the fields in
TimelineEntity.getRelatesToEntities()
If any of those related entities contain a ROW_KEY_SEPARATOR (currently "!")
then we'll have a problem parsing these entries correctly when reading them out.
I'll try to address that in the patch suggestion.

> Key: YARN-3706
> URL: https://issues.apache.org/jira/browse/YARN-3706
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Joep Rottinghuis
> Priority: Minor
>
> When reviewing YARN-3411 we noticed that we could change the class hierarchy
> a little in order to accommodate additional tables easily.
> In order to get ready for benchmark testing we left the original layout in
> place, as performance would not be impacted by the code hierarchy.
> Here is a separate jira to address the hierarchy.
