> I am getting corrupt parquet files as the result of a spark job. The write

> The job that generates this data partitions and sorts the data in a
> particular way to achieve better compression. If I don't partition and sort I
> have not been able to reproduce its behavior. It also only has this behavior
> on say 25% of the data. Most of the time simply rerunning the write job would
> cause the read error to go away but I have now run across cases where that
> was not the case. I am happy to give what data I can, or work with someone to
> run this down.
> I know this is a sub-optimal report, but I have not been able to randomly
> generate data to reproduce this issue. The data that trips this bug is
> typically 5GB+ post compression files.
