      Description

      API calls for certain point in time metrics are fetching data for 1 day.

      API:

      http://hostname:6188/ws/v1/timeline/metrics?metricNames=dfs.FSNamesystem.MissingReplOneBlocks%2Cdfs.FSNamesystem.TransactionsSinceLastCheckpoint%2Cdfs.FSNamesystem.MillisSinceLastLoadedEdits%2Cdfs.FSNamesystem.SnapshottableDi rectories%2Cdfs.FSNamesystem.LastCheckpointTime%2Cdfs.FSNamesystem.TotalFiles%2Cmaster.Master.QueueCallTime_median%2Cdfs.FSNamesystem.ExpiredHeartbeats%2Cdfs.FSNamesystem.PostponedMisreplicatedBlocks%2Cdfs.FSNamesystem.LastWrittenTransactionId%2Cdfs.FSNamesystem.Snapshots%2Cjvm.JvmMetrics.MemHeapCommittedM%2Cdfs.FSNamesystem.TransactionsSinceLastLog Roll%2Cmaster.Server.averageLoad%2Cjvm.JvmMetrics.MemHeapUsedM%2Cdfs.FSNamesystem.PendingDataNodeMessageCount%2Cmaster.AssignmentManger.ritCount%2Cdfs.FSNamesystem.StaleDataNodes&hostname=namenode_hostnamel&appId=NAMENODE
      

      Returned result on a cluster > 1 day old takes very long time.
      The call should return 1 latest value for each metric vs all values.
