Project: Apache Drill
Issue Type: Bug

Affects Versions: 0.9.0

Union all query over JSON data file fails when store.json.all_text_mode is set
to false, and same query returns correct results when store.json.all_text_mode
is set to true. Each JSON data file had only one type of object
{"key":<value>}, and the values in each of the JSON data files were of same
datatype. Test was executed on a 4 node cluster.

`dateData.json` union all select key from `doubleData.json` union all select
key from `intData.json` union all select key from `timeStmpData.json` union all
select key from `vrChrData.json`;
Query failed: RemoteRpcException: Failure while running fragment., For input

Then I set alter session set `store.json.all_text_mode`=true;
After setting son.all_text_mode to true, union all query returned correct
results.
