Chris Douglas commented on HADOOP-14216:
----------------------------------------
I only skimmed the patch, but this looks good. Just a few questions:
* I have no trouble believing this shows up in perf traces, but out of
curiosity, do you have any data on the improvement this effects?
* Filed HADOOP-14255; can we use the dependency added here to replace xmlenc?
* Can you update/add/link docs on the {{xi:fallback}} and {{xi:include}}
semantics? How do these interact with {{final}} config values?
