Pengcheng Xiong commented on HIVE-15161:
----------------------------------------
pushed to master. Thanks [~kgyrtkirk] for the patch. A similar change at the
tableproperties level would be a good idea but I can imagine that the most
difficult part would be the backward compatibility. ColumnStats' format is
relatively fixed and it is relatively easy to deal with the backward
compatibility. However, users can put almost anything in table properties,
which does not have a fix format.
> migrate ColumnStats to use jackson

> * json.org has license issues
> * jackson can provide a fully compatible alternative to it
> * there are a few flakiness issues caused by the order of the map entries of
> the columns...this cat be addressed, org.json api was unfriendly in this
> manner ;)
