Steve Loughran resolved HADOOP-19098.
-------------------------------------
Resolution: Fixed
> Vector IO: consistent specified rejection of overlapping ranges
> ---------------------------------------------------------------
>
> Key: HADOOP-19098
> URL: https://issues.apache.org/jira/browse/HADOOP-19098
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs, fs/s3
> Affects Versions: 3.3.6
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.3.9, 3.5.0, 3.4.1
>
>
> Related to PARQUET-2171 q: "how do you deal with overlapping ranges?"
> I believe s3a rejects this, but the other impls may not.
> Proposed
> FS spec to say
> * "overlap triggers IllegalArgumentException".
> * special case: 0 byte ranges may be short circuited to return empty buffer
> even without checking file length etc.
> Contract tests to validate this
> (+ common helper code to do this).
> I'll copy the validation stuff into the parquet PR for consistency with older
> releases
