[GitHub] [hadoop] steveloughran commented on pull request #3250: HADOOP-17825. Add BuiltInGzipCompressor

   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?
