Hi all, I lately noticed tags are often used to classify JIRAs. I was thinking we better explicitly document what tags are used and explain which tag means what. For instance, we documented "Contributing to JIRA Maintenance" at https://spark.apache.org/contributing.html before (thanks, Sean Owen) - this helps me a lot to managing JIRAs, and they are good standards for, at least, me to take an action.
It doesn't necessarily mean we should clarify everything but it might be good to document tags used often. We can leave this for committer's scope as well, if that's preferred - I don't have a strong opinion on this. My point is, can we clarify this in the contributing guide so that we can reduce the maintenance cost?
