Ryan Blue commented on PARQUET-1028:
------------------------------------

This was fixed by PARQUET-1065. The expected sort order for INT96 is now UNKNOWN, so stats are discarded.

> Found that the condition [here|https://github.com/apache/parquet-mr/blob/9d58b6a83aa79dcad01c3bcc2ec0a7db74ba83b1/parquet-column/src/main/java/org/apache/parquet/CorruptStatistics.java#L55] is missing a check for INT96. Since INT96 statis are also corrupt with old versions of Parquet, the code here shouldn't short-circuit return.
