@tasanuma Thanks for your review and comments! Yes, we have used the feature in our production cluster for nearly 1 year and it looks good. - `dfs.datanode.data.write.bandwidthPerSec`: Currently we have no limitation on user writes, and when user write bandwidth exceeds the bottleneck of hardware (NIC generally), the write will automatically slow down. - `dfs.datanode.ec.reconstruction.xmits.weight`: We keep it to default value of 0.5 - `dfs.datanode.data.transfer.bandwidthPerSec`: Same as the new added `dfs.datanode.ec.reconstruct.read.bandwidthPerSec`, we set it to half of available network traffic to be sure it will not affect user read/write. -- This is an automated message from the Apache Git Service.
