Design doc is wrong about default block placement policy. ---------------------------------------------------------
Key: HDFS-2547 URL: https://issues.apache.org/jira/browse/HDFS-2547 Project: Hadoop HDFS Issue Type: Bug Components: name-node Affects Versions: 0.20.1 Reporter: Harsh J Assignee: Harsh J Priority: Trivial Fix For: 0.24.0 Attachments: HDFS-2547.patch bq. For the common case, when the replication factor is three, HDFS's placement policy is to put one replica on one node in the local rack, another on a node in a different (remote) rack, and the last on a different node in the same *remote* rack. Should actually be: "and the last on a different node in the same *local* rack." -- This message is automatically generated by JIRA.
