ApplicationMaster.
This url if contains scheme then that will be used by resource manager
web application proxy otherwise it will default to http.ApplicationMaster@InterfaceAudience.Public @InterfaceStability.Stable public abstract void setTrackingUrl(String trackingUrl)
ApplicationMaster while
it is running. This is the web-URL to which ResourceManager or
web-application proxy will redirect client/users while the application and
the ApplicationMaster are still running.
If the passed url has a scheme then that will be used by the ResourceManager and web-application proxy, otherwise the scheme will default to http.
Empty, null, "N/A" strings are all valid besides a real URL. In case an url isn't explicitly passed, it defaults to "N/A" on the ResourceManager.
trackingUrl - tracking URLfor the ApplicationMaster@InterfaceAudience.Public @InterfaceStability.Unstable public Map<Set<String>,PlacementConstraint> getPlacementConstraints()
PlacementConstraint associated with the tags, i.e., each
SchedulingRequest that has those
tags will be placed taking into account the corresponding constraint.@InterfaceAudience.Public @InterfaceStability.Unstable public void setPlacementConstraints(Map<Set<String>,PlacementConstraint> placementConstraints)
SchedulingRequests
of this application.
The mapping is from a set of allocation tags to a
PlacementConstraint associated with the tags.
For example:
Map <
<hb_regionserver> -> node_anti_affinity,
<hb_regionserver, hb_master> -> rack_affinity,
