·
Inter process communication between nodes in a hadoop
cluster is implemented using Remote Procedure Calls (RPC).
Inter process communication happens in below three stages.
·
RPC protocol uses serialization to convert the message
from source data node into a binary stream data.
·
Binary stream data is transferred to the remote
destination node
·
Destination node then use De-serialization to convert
the binary stream data into object structured data and then it reads object
structured data.
