Bharath Kumarasubramanian closed SAMZA-2609. -------------------------------------------- > Data model changes to track lifecycle information of job coordinator > -------------------------------------------------------------------- > > Key: SAMZA-2609 > URL: https://issues.apache.org/jira/browse/SAMZA-2609 > Project: Samza > Issue Type: New Feature > Reporter: Bharath Kumarasubramanian > Assignee: Bharath Kumarasubramanian > Priority: Major > Fix For: 1.7 > > Time Spent: 1.5h > Remaining Estimate: 0h > > *Goal*: Implement the data model changes needed to track the lifecycle of AM. > *Description*: With AM HA, the new AM will regenerate job model, do job > planning and rewrite configurations and may have to spin up containers. The > new rewritten configurations, job model can change from the existing metadata > on which the containers are running. In order to handle this change of > metadata, we need a way to identify lifecycle of the AM and store some > information on the previous snapshot of the metadata. > *Changes*: > # Epoch identifier of the AM attempt so that we can determine if the new > attempt is part of the same lifecycle of AM or a new deployment lifecycle > # Additional information on the job model, configuration (potentially subset > of it) so that we can use this information to decide the course of action if > current metadata changed in comparison with the previous snapshot. -- This message was sent by Atlassian Jira (v8.3.4#803005)
