Ajay Kidave commented on HIVE-1609:
-----------------------------------
The parser was written in javacc since it is derived from similar functionality
in Owl. It was decided to reuse the existing parser when the filter
representation was discussed. If generated code is the issue, I can change the
build to pull javacc through ivy and not have the generated code checked in (it
is so currently because that was how it is in serde). Another possibility is we
can open another JIRA to change the parser implementation to ANTLR. Do let me
know what would work.
> Support partition filtering in metastore

> The metastore needs to have support for returning a list of partitions based
> on user specified filter conditions. This will be useful for tools which need
> to do partition pruning. Howl is one such use case. The way partition pruning
> is done during hive query execution need not be changed.
