在閱讀權威指南Hadoop的書的第四章中,我發現下面的句子:我們在hadoop中使用RPC或SSH進行進程間通信嗎?
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.
而且我知道,我們使用無密碼的SSH 爲機器之間的通信。
有人可以解釋我我們使用什麼RPC或SSH進行進程間通信?請澄清我的疑惑。
