> During RU, a failure occurred on "Client Components" group, "Service Check HBASE, MAPREDUCE2, HDFS, YARN" item.
> The UI presented me with a Retry button.  However, the server rejected this request:
> PUT /api/v1/clusters/ysru2/upgrades/5/upgrade_groups/4/upgrade_items/30
> {"UpgradeItem":{"status":"PENDING"}}
> {
>   "status" : 400,
>   "message" : "java.lang.IllegalArgumentException: Can not transition a stage from FAILED to PENDING"
> }
> I believe this is the current expected behavior since the failure is not marked to hold.  
> However, on any service check failure, the user should be able to retry (or maybe on any failure?  actions should be idempotent).
