Weiwei Wu commented on HDFS-13248: ---------------------------------- [~elgoiri] I have debug the trunk in my test cluster today, below is some debug information: In [^debug-info-1.jpeg], namenode receive a create request, the clientMachine is get from RPC, and which is router-IP. clientMachine will save to file's FileUnderConstructionFeature, and will use to decide the block location when namenode receive the addBlock request(In [^debug-info-2.jpeg]). > RBF: namenode need to choose block location for the client > ---------------------------------------------------------- > > Key: HDFS-13248 > URL: https://issues.apache.org/jira/browse/HDFS-13248 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Weiwei Wu > Priority: Major > Attachments: debug-info-1.jpeg, debug-info-2.jpeg > > > When execute a put operation via router, the NameNode will choose block > location for the router, not for the real client. This will affect the file's > locality. > I think on both NameNode and Router, we should add a new addBlock method, or > add a parameter for the current addBlock method, to pass the real client > information. -- 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
