{
  "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/upgrades/7?fields=Upgrade/*&_=1479742056069",
  "Upgrade" : {
    "cluster_name" : "c1",
    "create_time" : 1479741414972,
    "direction" : "DOWNGRADE",
    "downgrade_allowed" : true,
    "end_time" : -1,
    "exclusive" : false,
    "from_version" : "2.3.6.0-3796",
    "pack" : "nonrolling-upgrade-2.4",
    "progress_percent" : 56.666666666666664,
    "request_context" : "Downgrading to 2.3.6.0-3796",
    "request_id" : 7,
    "request_status" : "HOLDING_TIMEDOUT",
    "skip_failures" : false,
