And this can avoid that It consumes a lot of network bandwidth when SBN do uploads a new fsimage to ANN. When lots of network bandwidth was consumed, it will affect ANN to deal with normal RPC requests or sync edit logs. > This is a very useful setting when our fsimage file is very large. However current description of this setting is too simple, we can document this more. > {noformat} > > dfs.image.compress > false > Should the dfs image be compressed? > > > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
