      Description

      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)
