GzipCodec should read compression level etc from configuration

    Details

    • Type: Improvement
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 0.21.0
    • Component/s: io
    • Labels:
      None
    • Hadoop Flags:
      Incompatible change, Reviewed
    • Release Note:
      Provide an ability to configure the compression level and strategy for codecs. Compressors need to be 'reinited' with new characteristics such as compression level etc. and hence an incompatible addition to the api.

      Description

      GzipCodec currently uses the default compression level. We should allow overriding the default value from Configuration.

        static final class GzipZlibCompressor extends ZlibCompressor {
          public GzipZlibCompressor() {
            super(ZlibCompressor.CompressionLevel.DEFAULT_COMPRESSION,
                ZlibCompressor.CompressionStrategy.DEFAULT_STRATEGY,
                ZlibCompressor.CompressionHeader.GZIP_FORMAT, 64*1024);
          }
        }
