>
> Key: DRILL-1239
> URL: https://issues.apache.org/jira/browse/DRILL-1239
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - JSON
> Affects Versions: 0.4.0
> Environment: Seen both on standalone (OSX host, 16 GB RAM) as well as
> on cluster in AWS:
> 5 nodes, centos-6.5, 64GB RAM, 2 SSD's/node for mfs/dfs. Running MapR 3.1.1.

> 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>

> (<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.
