[GitHub] [pinot] mayankshriv opened a new pull request #8244: Support identifying Gzipped files by checking GZIP MAGIC_HEADER.

mayankshriv opened a new pull request #8244:
URL: https://github.com/apache/pinot/pull/8244


   The current record reader relies on file extension to be `.gz`, which may
   not always be the case. Implemented the following:
   
   - Util method that actually relies on `GZIPInputStream.GZIP_MAGIC` to identify
     a gzipped file.
   
   - Use the above method in RecordReader initialization.
   
   - Added unit test for JSONRecordReader using Gzipped JSON.
   
   Addresses the TODO in https://github.com/apache/pinot/pull/6321.

Review comment:
       Yeah, this one is a borderline for me too, so willing to make an `exception` (pun intended). Updated PR.

       Having seen the implementation, which essentially does just that, I have second thoughts

Review comment:
       Yeah, this one is a borderline for me too, so willing to make an `exception` (pun intended).

Review comment:
       Do try with resource to ensure the stream is closed

       try (InputStream inputStream = new FileInputStream(file)) {
         magic = inputStream.read() & 0xff | ((inputStream.read() << 8) & 0xff00);

Review comment:
       The suggestion seems to rely on exception being thrown as part of logic to determine if this is a Gzipped file or not, which doesn't seem like the best idea to me. Also, could you elaborate on what is the issue with checking magic header?

Review comment:
       Suggest directly trying to open a GZIPInputStream, which will do all the necessary validations (besides the magic short check which might not be enough)
   ```suggestion
       FileInputStream fileInputStream = new FileInputStream(dataFile);
       try {
         return new GZIPInputStream(fileInputStream);
       } catch (Exception e) {
         // NOTE: Cannot reuse the input stream because it might already be read
         fileInputStream.close();
         return new FileInputStream(dataFile);
       }

Review comment:
       My concern is mostly on the size of the header, which is a short that can potentially cause false positive. Reading `GZIPInputStream.readHeader()`, it actually performs much more checks including CRC. If both of you prefer the header check only, then I'm fine with it

Review comment:
       +1, I would check the header rather than assume then throw too
