Sangjin Lee commented on YARN-4053: ----------------------------------- Thanks [~varun_saxena] for pointing out an important issue. I would agree with [~gtCarrera9] that this is bit lower in priority compared to YARN-3814, but it's an important issue nonetheless. I'm just curious (and perhaps this is a totally dumb question for a HBase newbie), is there a way to specify that the value type is a numeric type when we create the table or the column family? Does HBase itself support something like that? > 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 > Attachments: YARN-4053-YARN-2928.01.patch > > > Currently HBase implementation uses GenericObjectMapper to convert and store > values in backend HBase storage.
