Elasticsearch 5.4.1 - availableProcessors is already set

Elastic Stack Elasticsearch

Hi,

I have upgraded elasticsearch from 5.4.0 to 5.4.1 and I have got this error:

java.lang.IllegalStateException: availableProcessors is already set to [8], rejecting [8]

It seems that the number of available processors is already configured in that moment.
Is there a fix for this?

Thanks,
Mihai

I can do something like this:

System.setProperty("es.set.netty.runtime.available.processors", "false");

but, for sure, is not the right fix.

May be open an issue in that case? @jasontedor WDYT?

Can you explain why it's already configured? Are you using Netty within your application outside of the use within the transport client?

5

Yes, I'm using Vert.x (a framework based on Netty).

6

Then you should indeed set es.set.netty.runtime.available.processors.

7

OK. Thank you!

What I wanted to emphasize was that the error has not been present on previous versions (<= 5.4.0).

I understand that, this feature wasn't available in versions of Netty that Elasticsearch <= 5.4.0 depended on.
