Ajay Kumar commented on HADOOP-15007:
-------------------------------------
[[email protected]],[~anu],[~elek] thanks for valuable feedback. Adding first
pass of patch with following changes:
* Replaced Enums with a common interface with Strings
* Logging moved at trace level. This should handle [~elek] case as well.( i.e
"I wouldn't like to see any warnings during my cluster startup as there are no
problems with my cluster even if the tags are misspelled. The warning should be
displayed during the build time for he developers/reviewers." )
* Added test case for invalid tags
* Updated javadocs in Configuration for tag functionality.
> Stabilize and document Configuration <tag> element

> We need to make sure that this feature is backwards compatible & usable in
> production. That's docs, testing, marshalling etc.
