Work Description: steveloughran commented on pull request #3250:
URL: https://github.com/apache/hadoop/pull/3250#issuecomment-895217443
One concern here: anything we have to worry about from a security
perspective? That is, if someone sends in something with an invalid range, does
that trigger allocation of massive buffers, etc, etc. commons-compress has had
security issues over time with things like .. in paths. I don't think there's
risk here, but it's worth considering: do we have to worry about malicious gz
files?

> Currently, GzipCodec only supports BuiltInGzipDecompressor, if native zlib is
> not loaded. So, without Hadoop native codec installed, saving SequenceFile
> using GzipCodec will throw exception like "SequenceFile doesn't work with
> GzipCodec without native-hadoop code!"
> Same as other codecs which we migrated to using prepared packages (lz4,
> snappy), it will be better if we support GzipCodec generally without Hadoop
> native codec installed. Similar to BuiltInGzipDecompressor, we can use Java
> Deflater to support BuiltInGzipCompressor.
