Ravi Prakash resolved HDFS-1195. -------------------------------- Resolution: Later Release Note: I think I like the proposal in HDFS-2537 more than this one. Also it hasn't seen any activity in forever. Closing. > Offer rate limits for replicating data > --------------------------------------- > > Key: HDFS-1195 > URL: https://issues.apache.org/jira/browse/HDFS-1195 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 0.20.2 > Environment: Linux, Hadoop 0.20.1 CDH > Reporter: Kevin Weil > > If a rack of Hadoop nodes goes down, there is a lot of data to re-replicate. > It would be great to have a configuration option to rate-limit the amount of > bandwidth used for re-replication so as not to saturate network backlinks. > There is a similar option for rate limiting the speed at which a DFS > rebalance takes place: dfs.balance.bandwidthPerSec. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
