[jira] [Assigned] (YARN-321) Generic application history service
[ https://issues.apache.org/jira/browse/YARN-321?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Yu Gao reassigned YARN-321: --- Assignee: Yu Gao Generic application history service --- Key: YARN-321 URL: https://issues.apache.org/jira/browse/YARN-321 Project: Hadoop YARN Issue Type: Improvement Reporter: Luke Lu Assignee: Yu Gao Attachments: AHS Diagram.pdf, ApplicationHistoryServiceHighLevel.pdf, Generic Application History - Design-20131219.pdf, HistoryStorageDemo.java The mapreduce job history server currently needs to be deployed as a trusted server in sync with the mapreduce runtime. Every new application would need a similar application history server. Having to deploy O(T*V) (where T is number of type of application, V is number of version of application) trusted servers is clearly not scalable. Job history storage handling itself is pretty generic: move the logs and history data into a particular directory for later serving. Job history data is already stored as json (or binary avro). I propose that we create only one trusted application history server, which can have a generic UI (display json as a tree of strings) as well. Specific application/version can deploy untrusted webapps (a la AMs) to query the application history server and interpret the json for its specific UI and/or analytics. -- This message was sent by Atlassian JIRA (v6.2#6252)
