Andrew Purtell commented on HBASE-10454:
----------------------------------------
PrefixTree doesn't compress tags, it encodes them using ... a prefix tree. This
is not tag compression using the (currently broken) custom dictionary
compression scheme employed by HFile. We need to differentiate. I argue the
patch here is not needed and confusing. Just update the documentation on prefix
tree to discuss how it handles tags, if that is missing.

> We always encode tags in case of Prefix tree now and so the code path, while
> decoding, not checking what is there in FileInfo. So functionally no issues
> now.
> If we do HBASE-10453 this change will be very important to make sure BC for
> old files.
