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. {code} 0: jdbc:drill:> select key from `charData.json` union all select key from `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 string: "itzVxYBb" [ f1f81073-161c-4f24-89e5-37379413b01b on centos-04.qa.lab:31010 ] [ f1f81073-161c-4f24-89e5-37379413b01b on centos-04.qa.lab:31010 ] Error: exception while executing query: Failure while executing query.
