Dear Hadoop/Yarn community, In Yarn, a container is represented as container_e*epoch*_*clusterTimestamp*_*appId*_*attemptId*_*containerId*
Regarding the last section, "containerId", as the sequential number of containers, I notice it does not start with 0, but 1. My question is: 1. Is that observation correct? 2. Sorry I do not find the code to support that. I read ContainerId.java and ContainerIdPBImpl.java but does not find the answer. Could you please show me the code path to support it staring with 1? 3. It seems counter-intuitive for me, as a programmer ^_^, who thinks the index should start with 0, rather than 1. If it is designed to start with 1, any background / thought / discussion to share? Thanks !!! -- 李响 Xiang Li
