huangzhaobo99 updated HDFS-17303: --------------------------------- Description: 1. The delay reported by DN to NN is an average delay of 3 hours, which confuses me. 2. There is a time limit for SlowNodes collected by nn, which is currently set to 5ms by default (dfs.datanode.slowpeer.low.threshold.ms), while the time threshold for printing SlowNode logs written downstream is 300ms (dfs.datanode.low.io.warning.threshold.ms). 3. Can changeing this window size and num to configurable param? > Make WINDOW_SIZE and NUM_WINDOWS configurable. > ---------------------------------------------- > > Key: HDFS-17303 > URL: https://issues.apache.org/jira/browse/HDFS-17303 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: huangzhaobo99 > Priority: Major > > 1.
