Laurent Goujon updated HADOOP-12677:
------------------------------------
Component/s: io
> DecompressorStream throws IndexOutOfBoundsException when calling skip(long)
> ---------------------------------------------------------------------------
>
> Key: HADOOP-12677
> URL: https://issues.apache.org/jira/browse/HADOOP-12677
> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Reporter: Laurent Goujon
>
> DecompressorStream.skip(long) throws an IndexOutOfBoundException when using a
> long bigger than Integer.MAX_VALUE
> This is because of this cast from long to int:
> https://github.com/apache/hadoop-common/blob/HADOOP-3628/src/core/org/apache/hadoop/io/compress/DecompressorStream.java#L125
> The fix is probably to do the cast after applying Math.min: in that case, it
> should not be an issue since it should not be bigger than the buffer size
> (512)
