Andries Engelbrecht commented on DRILL-2141: -------------------------------------------- When changing the query to use a different field to filter out JSON docs without the top level map a different error is received (similar to DRILL-2140). New Query: select t.retweeted_status.`user`.name as name, count(t.retweeted_status.id) as rt_count from `./nfl` t where t.`text` like '%RT_@%' group by t.retweeted_status.`user`.name order by count(t.retweeted_status.id) desc limit 10; Screen Output: Query failed: Query stopped., Undefined failure occurred.
