CentOS Linux release 7.4.1708 (Core)
java version "1.8.0\_152"
elasticsearch-5.6.3
I am brand new to elasticsearch and hence, this is a brand new install.
I installed elasticsearch using the rpm. After installation, I attempted to start elasticsearch using systemctl and I get the following in the logs:
> [2017-11-07T11:13:34,156][WARN][o.e.b.Natives] unable to load JNA native support library, native methods will be disabled.

`jna-4.4.0-1.jar` is in `/usr/share/elasticsearch/lib` and `libjnidispatch.so` is in `/usr/lib64/jna/libjnidispatch.so`.
I imagine if I can get `/usr/lib64/jna/libjnidispatch.so` into the resource path, things _should_ work but I am not sure how to do that.

Are you on a 32 bit system? We don't support 32 bit, and the lib it is searching for is 32 bit (com/sun/jna/linux-x86/libjnidispatch.so).

Also, the message is just a warning. The system can function without jna.

None of the dependencies installed is 32bit. The log is saying that elasticsearch is looking at that path not that I have 32bit java installed.
I'll have to look further down the logs to see why it won't start. I would still like to resolve this issue however.

If jna is looking for the 32bit lib, then it thinks the system is 32 bit.
