Thanks for your response, Bill. But I still feel confused that why the results from "dfsadmin -report" and "Web UI and fsck" is inconsistent?
Besides, I note that on the web ui (NameNode:50070), the "Heap Size" is 963MB. In my configuration, the NameNode and the JobTracker are on the same machine. I use the default configuration for heap size. Why the Heap Size shown on the web ui is not 1024MB?
