Subject namenode uestion
Date Fri, 08 May 2015 16:50:54 GMT
hi all,
I have an hdfs question, my understanding is, namenode sends a list of
datanodes to hadoop client to send data blocks based on replication
setting. The question is, does the list from namenode has IP addresses or
hostnames, or both of the datanodes.

NN -------> Client  ----> DN1 ------> DN2 ------> DN3
