> Certain queries on a JSON dataset throwing "Index out of bounds exception" errors when they process null arrays. The Null arrays are just returned fine when a variation of the query is attempted in such a way that different number of records are returned.
> The specific query that reproduces the issue is below.
> SELECT t.marketing_info.keywords FROM dfs.`/home/mapr/mobile.json` t where t.trans_info.purch_flag like 'true' and t.user_info.state like 'wa' 
> The issue seem to be occurring in the record below (note the empty keyword array). Modifying the keywords field to add a entry fixes the issue.
> {"trans_id":10710,"date":"07/19/2013","time":"13:27:22","user_info":{"cust_id":38533,"device":"IOS5","state":"wa"},"marketing_info":{"camp_id":1,"keywords":[]},"trans_info":{"prod_id":[104,307],"purch_flag":"true"}}
> Any variation of query done such as below works fine too.
> SELECT t.marketing_info.keywords FROM dfs.`/home/mapr/mobile.json` t where  t.user_info.state like 'wa' ;
> SELECT t.marketing_info.keywords FROM dfs.`/home/mapr/mobile.json` t where t.trans_info.purch_flag like 'true' ;
> SELECT t.marketing_info.keywords FROM dfs.`/home/mapr/mobile.json` t ;
