When the MapReduce shuffle service is started, it attempts to bind an IP address based on local host. If the MapReduce shuffle service is required to connect to a specific IP address, no configuration is available. The following description allows you to configure a connection to a specific IP address.
To bind a specific IP address to the MapReduce shuffle service, set the following parameters in the mapred-site.xml configuration file of the node where the NodeManager instance resides:
Parameter |
Description |
Default Value |
|---|---|---|
mapreduce.shuffle.address |
Indicates the specified address to run the shuffle service. The format is IP:PORT. The default value is empty. If this parameter is left empty, the local host IP address is bound. The default port number is 13562. NOTE:
If the value of PORT is different from that of mapreduce.shuffle.port, the mapreduce.shuffle.port value does not take effect. |
