[David Chen](https://issues.apache.org/jira/browse/PARQUET-5?#comment-14048077): Congratulations on entering Incubator! I have made some improvements to Parquet's Avro support in the past and would like to pick this up.

[Ryan Blue](https://issues.apache.org/jira/browse/PARQUET-5?#comment-14062647) / @rdblue: `[~davidzchen]`, feel free to pick this up! If you need any help with the parquet-avro code, let us know. Thanks!

[Steve Loughran](https://issues.apache.org/jira/browse/PARQUET-781?#comment-17850709) / @steveloughran: The strategy I propose for this is straightforward ```Java change type of committer field to OutputCommitter if (jobConf.get("option to use path output committer", false) { outputCommitter...

[Claire McGinty](https://issues.apache.org/jira/browse/PARQUET-2443?#comment-17823759) / @clairemcginty: I pushed a branch implementing the DataPage-as-Iterator idea, here:   However... it looks like ColumnReaderBase#checkRead works by continually invoking `readPage` [until the row group is fully consumed](https://github.com/apache/parquet-mr/blob/master/parquet-column/src/main/java/org/apache/parquet/column/impl/ColumnReaderBase.java#L653-L676),...

[Zhenxiao Luo](https://issues.apache.org/jira/browse/PARQUET-131?#comment-14208956) / @zhenxiao: @brockn Thanks a lot for the comment. I will update the ColumnVector interface, with getters and setters, and getTypes. And all primitive type Vectors are left...

[Jacques Nadeau](https://issues.apache.org/jira/browse/PARQUET-131?#comment-14210025) / @jacques-n: Few thoughts: - I agree with Brock's general comments about having to avoid a parquet canonical representation of the in memory data structure. - For the...

[Zhenxiao Luo](https://issues.apache.org/jira/browse/PARQUET-131?#comment-14215442) / @zhenxiao: @brockn The gist is updated with ColumnVector interface. We are still discussing with the Drill team about whether to use Primitive Arrays, or ByteBuffer, or byte[]...
