> On 900 node cluster we did an express upgrade from HDP-2.3 to HDP-2.4. After
> install packages was done, the action to do express upgrade was clicked and
> the POST call to trigger EU took more than 3 minutes. Due to this, UI timed
> out and showed an error message saying EU failed - however, in the backend it
> continued and correctly started the upgrade.
> Services installed were:
> * HDFS
> * YARN
> * MapReduce2
> * Tez
> * Hive
> * HBase
> * Pig
> * Oozie
> * ZooKeeper
> * Ambari Metrics
