The setting value is not persistent and not stored in > configuration file. The different datanodes could their different default or > former setting in configuration. > When we suggested to develop a schedule balancer task which runs at midnight > everyday. We set a larger bandwidth for it and hope to reset the value after > finishing. However, we found it difficult to reset the different setting for > different datanodes as the setBalancerBandwidth command can only set the same > value to all datanodes. If we want to use unique setting for every datanode, > we have to reset the datanodes. > So it would be useful to have a command to synchronize the setting with the > configuration file. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
