No longer using generics. Removed ValueConverterImpl. And changed add method to {{Number add(Number num1, Number num2, Number...numbers)}} > 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 > Labels: yarn-2928-1st-milestone > Attachments: YARN-4053-YARN-2928.01.patch, YARN-4053-YARN-2928.02.patch, YARN-4053-feature-YARN-2928.03.patch, YARN-4053-feature-YARN-2928.04.patch, YARN-4053-feature-YARN-2928.05.patch, YARN-4053-feature-YARN-2928.06.patch, YARN-4053-feature-YARN-2928.07.patch > > > 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)
