> Using a JSON file with contents like so for each record:
> {code}:
> {"trans_id":999999,"date":"11/03/2012","time":"09:07:05","user_info":{"cust_id":2,"device":"AOS4.3","state":"tx"},"marketing_info":{"camp_id":14,"keywords":["it","i","wants","yes","things","few","like"]},"trans_info":{"prod_id":[167,145,5,487,290],"purch_flag":"false"}}
> {code}
> First I set the following to get more verbose output:
> {quote}
> 0: jdbc:drill:> alter session set `exec.errors.verbose`=true;
> {quote}
> Then performed a simple select via sqlline:
> {quote}
> select * from dfs.`/mapr/drillram/JSON/large/mobile.json`;
> <50,000+ rows of output>

> If I re-run the same query against a smaller version of the same dataset (<50,000
records), I don't have the issue.  So far I've tried modifying the  DRILL_MAX_DIRECT_MEMORY
and
> DRILL_MAX_HEAP variables to see if I could find something that works, but neither seem
to make a difference.  Note: the error appears the same if I run on standalone mode.
