Brahma Reddy Battula commented on HDFS-13248: --------------------------------------------- thanks all for useful discussion. Do you guys ran any MR job and seen % of data locality.? any chances application will *always* try to connect to different router.(random order can be disabled).? > 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: Wu Weiwei > Assignee: Íñigo Goiri > Priority: Major > Attachments: HDFS-13248.000.patch, HDFS-13248.001.patch, > HDFS-13248.002.patch, HDFS-13248.003.patch, HDFS-13248.004.patch, > HDFS-13248.005.patch, HDFS-Router-Data-Locality.odt, RBF Data Locality > Design.pdf, clientMachine-call-path.jpeg, 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.
