方法详细资料

getRpcUrl

String getRpcUrl(String hostname,
                 int port,
                 String endpointName,
                 AddressResolution addressResolution,
                 org.apache.flink.configuration.Configuration config)
          throws UnknownHostException

Constructs an RPC URL for the given parameters, that can be used to connect to the targeted RpcService.

参数:

hostname - The hostname or address where the target RPC service is listening.

port - The port where the target RPC service is listening.

endpointName - The name of the RPC endpoint.

addressResolution - Whether to try address resolution of the given hostname or not. This allows to fail fast in case that the hostname cannot be resolved.

config - The configuration from which to deduce further settings.

返回:

The RPC URL of the specified RPC endpoint.

抛出:

UnknownHostException

getInetSocketAddressFromRpcUrl

InetSocketAddress getInetSocketAddressFromRpcUrl(String url)
                                          throws Exception

Returns an InetSocketAddress corresponding to the given RPC url.

参数:

url - RPC url

返回:

inet socket address

抛出:

Exception - if the URL is invalid

getMaximumMessageSizeInBytes

long getMaximumMessageSizeInBytes(org.apache.flink.configuration.Configuration config)

Returns the maximum number of bytes that an RPC message may carry according to the given configuration. If no limit exists then Long.MAX_VALUE should be returned.

参数:

config - Flink configuration

返回:

maximum number of bytes that an RPC message may carry
