> The Hadoop's LZ4 compression codec now depends on lz4-java. There two type of
> compressor in lz4, `fastCompressor` and `highCompressor`. The default lz4
> compressor in hadoop is fastCompressor, we also can use highCompressor by
> using config `IO_COMPRESSION_CODEC_LZ4_USELZ4HC_DEFAULT`
>
> When we want to use highCompressor in hadoop, we only can use the default
> compression level, which is level 9. while highCompressor in lz4-java
> supports compression level from 1 to 17.
>
> I think we can set a configuration to let users to choose different
> compresssionLevel for lz4 highCompressor.
