Jonathan Hurley commented on AMBARI-6780:
-----------------------------------------
The heart of the problem was the metrics regex and matching. Things that were
being done wrong:
- Creating categories from a given property ID (incorrect category creation
when regex/methods were present)
- Searching using startsWith or contains(...) when a regular expression was
needed
- Not matching all potential subproperties when retrieving the metrics to
request
We never saw these issues in YARN because of:
- There were no metrics with the same name defined both with and without
regular expressions
- Luck; the patterns being matched on appears first, and thus the
startsWith(...) was working
> SOURCE and SINK metrics not working on host-component
