Ivan Gozali commented on PARQUET-686:
-------------------------------------
Hi all, just curious if this issue is also resolved in Parquet 1.8.2, which is
what Spark 2.2.0 currently uses?
> Allow for Unsigned Statistics in Binary Type

> Key: PARQUET-686
> URL: https://issues.apache.org/jira/browse/PARQUET-686
> Project: Parquet
> Issue Type: Bug
> Components: parquet-format
> Reporter: Andrew Duffy
> Assignee: Ryan Blue
> Fix For: 1.9.0
>
>
> BinaryStatistics currently only have a min/max, which are compared as signed
> {{byte[]}}. However, for real UTF8-friendly lexicographic comparison, e.g.
> for string columns, we would want to calculate the BinaryStatistics based off
> of a comparator that treats the bytes as unsigned.
