----------------------------------------

             Summary: Properties are present in Hive/Configs/Advanced hive-site, but not available on backend
                 Key: AMBARI-7829
                 URL: https://issues.apache.org/jira/browse/AMBARI-7829
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 1.7.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
            Priority: Critical
             Fix For: 1.7.0


During stack upgrade 2.0 -> 2.1(ambari 1.7.0). On step
{code}
3. Complete the Stack Upgrade
Make the following config changes required for Application Timeline Server. Use the Ambari web UI to navigate to the service dashboard and add/modify the following configurations:

YARN (Custom yarn-site.xml)

yarn.timeline-service.leveldb-timeline-store.path=/var/log/hadoop-yarn/timeline
yarn.timeline-service.leveldb-timeline-store.ttl-interval-ms=300000
** If you are upgrading to HDP 2.1.3, use the following setting: yarn.timeline-service.store-class=org.apache.hadoop.yarn.server.timeline.LeveldbTimelineStore**
** If you are upgrading to HDP 2.1.2, use the following setting: yarn.timeline-service.store-class=org.apache.hadoop.yarn.server.applicationhistoryservice.timeline.LeveldbTimelineStore **
yarn.timeline-service.ttl-enable=true
yarn.timeline-service.ttl-ms=2678400000
yarn.timeline-service.generic-application-history.store-class=org.apache.hadoop.yarn.server.applicationhistoryservice.NullApplicationHistoryStore
yarn.timeline-service.webapp.address={PUT_THE_FQDN_OF_ATS_HOST_NAME_HERE}:8188
yarn.timeline-service.webapp.https.address={PUT_THE_FQDN_OF_ATS_HOST_NAME_HERE}:8190
yarn.timeline-service.address={PUT_THE_FQDN_OF_ATS_HOST_NAME_HERE}:10200

HIVE (hive-site.xml)
hive.execution.engine=mr
hive.exec.failure.hooks=org.apache.hadoop.hive.ql.hooks.ATSHook
hive.exec.post.hooks=org.apache.hadoop.hive.ql.hooks.ATSHook
hive.exec.pre.hooks=org.apache.hadoop.hive.ql.hooks.ATSHook
hive.tez.container.size={map-container-size}
        *If mapreduce.map.memory.mb > 2GB then set it equal to mapreduce.map.memory. Otherwise, set it equal to mapreduce.reduce.memory.mb*
hive.tez.java.opts="-server -Xmx" + Math.round(0.8 * map-container-size) + "m -Djava.net.preferIPv4Stack=true -XX:NewRatio=8 -XX:+UseNUMA -XX:+UseParallelGC"
{code}
I can see all properties which i need to add, are already in UI(Hive/Configs/Advanced hive-site). But realy, we don't have these properties on backend. They are not available in hive-site.xml, command-*.json and etc. It can confuse user. UI should show only real properties that are applied on BE
