Subject Re: How to get Container ID from configuration
Date Fri, 06 Mar 2015 01:08:10 GMT
Hey Jae,

We expose this in SamzaContainerContext. Unfortunately, this class never
gets exposed to the StreamTask. The plan was to expose this class via
TaskContext, but we haven't done that yet.

Have you tried using System.getProperty("")?
