> I tried a select * on a json file which contained a single array of strings. Drill fails to read the file if the array has 2000 elements. However it works for an array size of 1500. So I am not sure if it is a known limitation or a bug.
> Query :
> {code}
> jdbc:drill:schema=dfs.drillTestDir> select * from `data-shapes/wide-records/single/wide-record1.json`;
> Query failed: Query stopped., Record was too large to copy into vector. [ 5b320c2f-fff3-4de5-8095-8043c30510fd on qa-node191.qa.lab:31010 ]
> {code}
> I attached the data file and the error log. Let me know if you have any questions.
