             Summary: Bulk Ops only targets a maximum of "page size" hosts
                 Key: AMBARI-6311
                 URL: https://issues.apache.org/jira/browse/AMBARI-6311
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.6.1
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
            Priority: Blocker
             Fix For: 1.6.1


It seems that the max number of target hosts for a bulk operation is capped by the current "page size" on the Hosts page.

For example, on the 2K cluster with 2K DataNodes:
* Go to Hosts page
* Click on Actions.
* Either going to Filtered Hosts (2005) or All Hosts (2005), select "DataNodes > Stop"
* A confirmation popup tells me that 50 DataNodes are about to be stopped.  This should have been ~ 2000 DataNodes instead.  50 is the current page size on the Hosts page that I set.

Another scenario:
* Set page size to 50.
* Select 100 hosts using "check all", "next page", then "check all" 
* Go to "Actions > Selected Hosts > DataNodes > Stop".  
* Again, it tries to perform actions on only 50 DataNodes.
