New Install: unable to load JNA native support library

Elastic Stack Elasticsearch
1

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).

3

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

4

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.
