add net.logstash.log4j2.JSONEventLayoutV1 for log4j2 support

• moved HostData to new package as it seemed misplaced with the new log4j2 package

I noticed when using this. You'd loose the logging level because its always an empty map.

Hi Michael,

Thanks for this !
I think I found an issue in your code: the log-level doesn't end up in my log-files: the key is present but the value is always an empty object, like this "level":{}

I tried to reproduce this with your unit tests (net.logstash.log4j2.JSONEventLayoutV1Test)
but it seem that these tests are actually using the log4j 1.x appender and layout.

Are you actively using your patch ?
Or did you find another solution ?

Are you actively using your patch?

I was to, but then priorities shifted 😐 - so I guess one has to look at the issue sometime…

[maartenbosteels]

I fixed the issue with the log-level and discovered that your unit tests were using the log4j 1.x code.
So I removed the log4j 1.x code and fixed the unit tests as well

Will this PR be actioned and released anytime soon? The DNSBelgium fork appears to work.

Hello,
Are these changes planned to be merged anytime soon?
Kind regards

@cmpsoares91 as i wrote above: this is more than stale and AFAIR i never even ended up really using the code. so i consider this stale and probably outdated…
