Description
When querying data through Hive's JDBC driver, float values are automatically converted to doubles and will slightly differ from values seen when directly querying the data using a textual SQL interface.
Please note that by slight difference I don't only mean additional zeroes at the end, but an actual numeric difference in the displayed value. This is the result of the different precision used when displaying double values, as discussed here, for example.
