Hi, all I'm confused by a question that "how does the HDFS decide where to put the data blocks "
I mean that the user invokes some commands like "./hadoop put ***", we assume that this file consistes of 3 blocks, but how HDFS decides where these 3 blocks to be put? Most of the materials don't involve this issue, but just introduce the data replica where talking about blocks in HDFS, can anyone give me some instructions?
