--------------------------------------
Summary: Allow change from integer to double type and vice versa
in JSON reader
Key: DRILL-1255
URL: https://issues.apache.org/jira/browse/DRILL-1255
Project: Apache Drill
Issue Type: Improvement
Reporter: Jason Altekruse
Currently the JSON reader for drill will fail if there is any schema change in
a file. For the time being, this is expected for a significant change in type,
such as a change between types without clear implicit casting rules, such as a
change between any combination of string, bool, or numeric types. We however do
want to support changing from an integer to a double type (any number with a
decimal point is read as a double value) or vice versa should be handled.
