|
|
RPC
|
|
|
RMI
|

IP Exchange

Explanation:
Detailed explanation-1: -In Hadoop, interprocess communication between nodes in the system is implemented using remote procedure calls (RPCs). The RPC protocol uses serialization to render the message into a binary stream to be sent to the remote node, which then deserializes the binary stream into the original message.
Detailed explanation-2: -All communication between Namenode and Datanode is initiated by the Datanode, and responded to by the Namenode. The Namenode never initiates communication to the Datanode, although Namenode responses may include commands to the Datanode that cause it to send further communications.
Detailed explanation-3: -cp: Copy files from one directory to another within HDFS, similar to Unix cp command.
