I am running ELK stack with Docker for log management with current configuration of ES 1.7, Logstash 1.5.4 and Kibana 4.1.4. Now I am trying to upgrade Elasticsearch to 2,4 by using tar.gz file with Docker. As ES 2.X, does not allow running it as root user, I have used -Des.insecure.allow.root=true option while running the elasticsearch service, yet my container don't start. The logs don't mention any problem.

Native thread-sleep not available.
This will result in much slower performance, but it will still work.
You should re-install spawn-sync or upgrade to the lastest version of node if possible.
Check /opt/log-management/ESExportWrapper/node_modules/sync-request/node_modules/spawn-sync/error.log for more details
