> It would be useful to have a query option to allow setting the default file format. This would allow the file format to be overridden globally or per-session. We already have a COMPRESSION_CODEC option. 
> We had some discussion on IMPALA-2210 related to this.
> The current default is hardcoded in the code: https://github.com/apache/impala/blob/64e6719870db5602a6fa85014bc6c264080b9414/fe/src/main/java/org/apache/impala/analysis/TableDef.java#L136 https://github.com/apache/impala/blob/64e6719870db5602a6fa85014bc6c264080b9414/fe/src/main/java/org/apache/impala/analysis/TableDef.java#L145
