Simplify parameter passing to Application Master from Client. SImplify approach to pass info such appId, ClusterTimestamp and failcount required by App Master. ----------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-3055 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3055 Project: Hadoop Map/Reduce Issue Type: Bug Components: mrv2 Affects Versions: 0.23.0 Reporter: Hitesh Shah Priority: Minor Fix For: 0.23.0 The Application master needs the application attempt id to register with the Applications Manager. To create an appAttemptId object, the appId object(needs cluster timestamp and app id) and failCount are needed. Currently, all clients need to pass in the appId, cluster timestamp and fail count to the app master for the required objects to be constructed. We could look at simplifying this by providing either placeholders that would have values replaced by the app master launcher or setting it into the environment ( although that requires a set of whitelisted env vars that can only be set by the yarn framework ). -- This message is automatically generated by JIRA.
