Executive summary is that the original ATS has scaling issues, and we need an interim solution until the [ATSv2 effort|https://issues.apache.org/jira/browse/YARN-2928] is ready. The basic idea is to have clients and jobs write entities to HDFS rather than posting them to a single, central web service to better handle the write load from a large cluster running lots of jobs concurrently. We need something like this to get a working Tez UI on our large clusters and can't wait until ATSv2 is ready. > YARN Timeline Service plugin: ATS v1.5 > -------------------------------------- > > Key: YARN-4233 > URL: https://issues.apache.org/jira/browse/YARN-4233 > Project: Hadoop YARN > Issue Type: New Feature > Components: timelineserver > Reporter: Xuan Gong > Assignee: Xuan Gong > > Copy the description from YARN-3942: Timeline store to read events from HDFS > This adds a new timeline store plugin that is intended as a stop-gap measure to mitigate some of the issues we've seen with ATS v1 while waiting for ATS v2. The intent of this plugin is to provide a workable solution for running the Tez UI against the timeline server on a large-scale clusters running many thousands of jobs per day. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
