Alex Levenson commented on PARQUET-162:
---------------------------------------
[~skrishnan] points out that passing a wrong column name actually causes all
columns to be dropped, which is bad news
> ParquetThrift should throw when unrecognized columns are passed to the column
> projection API

> Reporter: Alex Levenson

> It appears that giving wrong / unrecognized column names to the projection
> API doesn't fail fast or even report that the columns were unrecognized at
> all.
> We should also log at start up what columns are being projected, this is
> useful info to have in the logs.
