>                 Key: PARQUET-1559
>                 URL: https://issues.apache.org/jira/browse/PARQUET-1559
>             Project: Parquet
>          Issue Type: Improvement
>          Components: parquet-mr
>    Affects Versions: 1.10.1
>            Reporter: Victor
>            Priority: Major
>
> I'm not exactly sure this is compliant with the way parquet works, but I have the following need:
>  * I'm using parquet-avro to write to a parquet file during a long running process
>  * I would like to be able from time to time to access the already written data
> So I was expecting to be able to flush manually the file to ensure the data is on disk and then copy the file for preliminary analysis.
> If it's contradictory to the way parquet works (for example there is something about metadata being at the footer of the file), what would then be the alternative?
> Closing the file and opening a new one to continue writing?
> Could this be supported directly by parquet-mr maybe? It would then write multiple files in that case.
