Hi. How to monitor the block transmission log of datanodes?
A more detailed example: My hdfs block size is 128MB. I have a file stored on hdfs with size 167.08MB. Also, I have a client, requesting the whole file with three splits, e.g., hdfs://myserver:9000/myfile:0+58397994 (0-56MB) hdfs://myserver:9000/myfile:58397994+58397994 (56MB-112MB) hdfs://myserver:9000/myfile:116795988+58397994 (112MB-168MB) The situation is kinda fixed and I cannot modify the split size. Nevertheless, I'd like to know what block tranmission is happening under the earth.
