DefaultHostNameSupplier

public DefaultHostNameSupplier(InetAddress inetAddress)

方法详细资料

getHostName

public String getHostName()

Gets the hostname of the TaskManager. The hostname derives from the fully qualified domain name (FQDN, see TaskManagerLocation.getFQDNHostname()):

• If the FQDN is the textual IP address, then the hostname is also the IP address
• If the FQDN has only one segment (such as "localhost", or "host17"), then this is used as the hostname.
• If the FQDN has multiple segments (such as "worker3.subgroup.company.net"), then the first segment (here "worker3") will be used as the hostname.

指定者:

getHostName 在接口中 TaskManagerLocation.HostNameSupplier

返回:

The hostname of the TaskManager.

getFqdnHostName

public String getFqdnHostName()

Returns the fully-qualified domain name the TaskManager. If the name could not be determined, the return value will be a textual representation of the TaskManager's IP address.

指定者:

getFqdnHostName 在接口中 TaskManagerLocation.HostNameSupplier

返回:

The fully-qualified domain name of the TaskManager.
