getRunningApplications

public List<org.apache.hadoop.yarn.api.records.ApplicationId> getRunningApplications()

Description copied from class: RegisterNodeManagerRequest

We introduce this here because currently YARN RM doesn't persist nodes info for application running. When RM restart happened, we cannot determinate if a node should do application cleanup (like log-aggregation, status update, etc.) or not.

When we have this running application list in node manager register request, we can recover nodes info for running applications. And then we can take actions accordingly

Specified by:

getRunningApplications in class RegisterNodeManagerRequest

Returns:

running application list in this node

setRunningApplications

public void setRunningApplications(List<org.apache.hadoop.yarn.api.records.ApplicationId> apps)

Description copied from class: RegisterNodeManagerRequest

Setter for RegisterNodeManagerRequest.getRunningApplications()

Specified by:

setRunningApplications in class RegisterNodeManagerRequest

Parameters:

apps - running application in this node

getNMContainerStatuses

public List<NMContainerStatus> getNMContainerStatuses()

Specified by:

getNMContainerStatuses in class RegisterNodeManagerRequest

setContainerStatuses

public void setContainerStatuses(List<NMContainerStatus> containerReports)

Specified by:

setContainerStatuses in class RegisterNodeManagerRequest

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object

getNMVersion

public String getNMVersion()

Specified by:

getNMVersion in class RegisterNodeManagerRequest

setNMVersion

public void setNMVersion(String version)

Specified by:
