Varun Saxena commented on YARN-4053: ------------------------------------ [~gtCarrera9], it is blocking metric filter implementation. We can discuss offline regarding what all you are looking at for POC of web UI. I can focus on that part first. I was under the assumption only YARN-3814 is required for Web UI POC as of now. > Change the way metric values are stored in HBase Storage > -------------------------------------------------------- > > Key: YARN-4053 > URL: https://issues.apache.org/jira/browse/YARN-4053 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Affects Versions: YARN-2928 > Reporter: Varun Saxena > Assignee: Varun Saxena > > Currently HBase implementation uses GenericObjectMapper to convert and store > values in backend HBase storage. This converts everything into a string > representation(ASCII/UTF-8 encoded byte array). > While this is fine in most cases, it does not quite serve our use case for > metrics. > So we need to decide how are we going to encode and decode metric values and > store them in HBase. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
