Description

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.
