Hi. I have 2 questions about HDFS performance:
1) How fast are the read and write operations over network, in Mbps per second? 2) If the chunk server is located on same host as the client, is there any optimization in read operations? For example, Kosmos FS describe the following functionality: "Localhost optimization: One copy of data is placed on the chunkserver on the same host as the client doing the write Helps reduce network traffic" Regards.
