Zoltan Haindrich commented on HIVE-15161:
-----------------------------------------
[~pxiong] can you please take a look at these changes?
and one more thing: there are a few cases when there "column_stats" is present;
but "basic_stats" is false - and hence omitted...they seem to be a bit odd -
should I look after these ?
{code}
autoColumnStats_4.q.out: COLUMN_STATS_ACCURATE
{\"COLUMN_STATS\":{\"a\":\"true\",\"b\":\"true\"}}
{code}
> migrate ColumnStats to use jackson

> * json.org has license issues
> * jackson can provide a fully compatible alternative to it

> the columns...this cat be addressed, org.json api was unfriendly in this
> manner ;)
