Hi,

I got following warnings, when running elasticsearch on arm platform:

After that ES boots and is accessible

Are these warnings critical? Will them degrade performance?
Any Idea how I can get JNA running on arm?

Thanks, Andreas

The warning is not critical. However, note that 32 bit support is removed in 6.0. The jna lib is shipped with aarch64 support though (although there is no official support for Elasticsearch on any arm, 32 or 64 bit).

thanks, ok, then I will ignore these messages
