             Summary: Stack Upgrade from HDP 2.1 or 2.2 to 2.3 to preserve configs for AppTimelineServer ATS version 1.0
                 Key: AMBARI-14056
                 URL: https://issues.apache.org/jira/browse/AMBARI-14056
             Project: Ambari
          Issue Type: Bug
            Reporter: Alejandro Fernandez
            Priority: Critical


HDP 2.3.4.0 has support for both AppTimelineServer v1.0 and v1.5
The HDP 2.3 stack definition will make ATS v1.5 the default for configs.
This means that any stack upgrade that modifies the configs and upgrades to version x where 2.3.0.0 <= x < 2.3.4.0 will fail since those binaries only support ATS v1.0 but the configs are for ATS 1.5.

The fix is to modify the following upgrade packs
HDP 2.1 -> 2.3 in nonrolling
HDP 2.2 -> 2.3 in both rolling and nonrolling

So that they preserve the ATS v1.0 configs.
For tez-site, keep
{code}
tez.history.logging.service.class = org.apache.tez.dag.history.logging.ats.ATSHistoryLoggingService
{code}

For yarn-site, keep 
{code}
yarn.timeline-service.version = 1.0
yarn.timeline-service.store-class = org.apache.hadoop.yarn.server.timeline.LeveldbTimelineStore
{code}
and it's ok to add the HDP 2.3 configs that are not being used, e.g.,
{code}
yarn.timeline-service.entity-group-fs-store.group-id-plugin-classes = org.apache.tez.dag.history.logging.ats.TimelineCachePluginImpl
yarn.timeline-service.entity-group-fs-store.summary-store = org.apache.hadoop.yarn.server.timeline.RollingLevelDBTimelineStore
yarn.timeline-service.entity-group-fs-store.scan-interval-seconds = 60
yarn.timeline-service.entity-group-fs-store.cleaner-interval-seconds = 3600
yarn.timeline-service.entity-group-fs-store.retain-seconds = 604800
yarn.timeline-service.entity-group-fs-store.active-dir = /ats/active/
yarn.timeline-service.entity-group-fs-store.done-dir = /ats/done/
{code}
