Sangjin Lee commented on YARN-5093:
-----------------------------------
Yes, I think you're right. I initially thought this might be a UI issue, but
the data also seems to be overwritten as 0. From the application table:
{noformat}
yarn_cluster!sjlee!Sleep
job!\x7F\xFF\xFE\xAB?\x98I\xF7!\x7F\xFF\xFE\xAB?\x9A\xE6~\x7F\xFF\
column=i:created_time, timestamp=1463527180684000000,
value=\x00\x00\x00\x00\x00\x00\x00\x00
{noformat}
> created time shows 0 in most REST output

> Key: YARN-5093
> URL: https://issues.apache.org/jira/browse/YARN-5093
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Sangjin Lee
> Assignee: Varun Saxena
> Priority: Critical
> Labels: yarn-2928-1st-milestone
>
> When querying the REST API, I find that the created time value is returned as
> "0" for most of the output. It includes:
> - flow activity and flow runs in the flow activity page
> - apps in the application page
> - entities in the entity page
> For example, in the flow activity page,
> {noformat}
> {
> metrics: [ ],
> events: [ ],
> id: "yarn_cluster/1463356800000/sjlee@ds-date",
> type: "YARN_FLOW_ACTIVITY",
> createdtime: 0,
> flowruns: [
> {
> metrics: [ ],
> events: [ ],
> id: "sjlee@ds-date/1463435661428",
> type: "YARN_FLOW_RUN",
> createdtime: 0,
> info: {
> SYSTEM_INFO_FLOW_VERSION: "1",
> SYSTEM_INFO_FLOW_RUN_ID: 1463435661428,
> SYSTEM_INFO_FLOW_NAME: "ds-date",
> SYSTEM_INFO_USER: "sjlee"
> },
> isrelatedto: { },
> relatesto: { }
> }
> ],
> info: {
> SYSTEM_INFO_CLUSTER: "yarn_cluster",
> UID: "yarn_cluster!sjlee!ds-date",
> SYSTEM_INFO_FLOW_NAME: "ds-date",
> SYSTEM_INFO_DATE: 1463356800000,
> SYSTEM_INFO_USER: "sjlee"
> },
> isrelatedto: { },
> relatesto: { }
> }
> {noformat}
> The only page that appears to show the proper created time value is the flow
> run page.
