I’m having a hard time understanding exactly what your current setup is, so here are the details:
- the agent code has been modified to communicate via SSL. That code is downloaded to each launched container from /slider/agent HDFS folder (slider-agent.tar.gz). If you have installed an up to date version of slider you’ll need to update that file in HDFS. - The AM has been updated to support SSL. If you’ve reinstalled slider then that code should be added to the AM as a local resource by yarn If those two conditions are met, then perhaps you are actually having and issue with openssl - it is being leveraged for certificate and keystone generation of the server side (by default it is one way SSL so there should be no need for the client to generate these resources) For more information on the SSL setup see http://slider.incubator.apache.org/design/ssl_implementation.html — Jon On Aug 15, 2014, at 11:11 AM, Rui Zhang <rzh...@vertica.com> wrote: > The first error solved.
