We have two similar formats because they were designed at roughly the same
time by different teams with similar, but not identical goals. Part of
having a thriving ecosystem is that there are competitors, which creates
some user confusion, but makes the ecosystem stronger. (Can someone please
make a competitor for Oozie? *grin*)

Hive and LLAP do support Parquet precisely because the developers want to
be able to process everyone's data. The Impala project is free to make
their own choices about what to work on.
