> This is because there are two open calls in the HFile: one with checksum and
> another for without checksum support in v2:
> see the method in HFile:createReaderWithEncoding()
> {code}
> FSDataInputStream fsdis = fs.open(path);
> FSDataInputStream fsdisNoFsChecksum = fsdis;
> // If the fs is not an instance of HFileSystem, then create an
> // instance of HFileSystem that wraps over the specified fs.
> // In this case, we will not be able to avoid checksumming inside
> // the filesystem.
> if (!(fs instanceof HFileSystem)) {
> hfs = new HFileSystem(fs);
> } else {
> hfs = (HFileSystem)fs;
> // open a stream to read data without checksum verification in
> // the filesystem
> fsdisNoFsChecksum = hfs.getNoChecksumFs().open(path);
> }
