Hi List, I need to explain an higher than expected throughput (bandwidth) for a HDFS C API Client. Specifically, the client is getting bandwidth higher than its link rate :). The client is first writing a 512 MB file followed by reading the entire file back. The file read is what's getting the higher than link rate bandwidth. I assume this is a consequence of caching? Is this done by HDFS or by Linux?
Thanks for any help, -- - Patrick Donnelly
