Julien Le Dem updated PARQUET-2:
--------------------------------
Component/s: parquet-mr
Description:
Pull request: https://github.com/apache/incubator-parquet-mr/pull/3
Original from the old repo: Parquet/parquet-mr#410
These changes allow primitive types to be requested as different types than
what is stored in the file format using a flag to turn off strict type checking
(default is on). Types are cast to the requested type where possible and will
suffer precision loss for casting where necessary (e.g. requesting a double as
an int).
No performance penalty is imposed for using the type defined in the file type.
A flag exists to
A 6x6 test case is provided to test conversion between the primitive types.
