[jira] Updated: (HADOOP-1047) TestReplication fails because DFS does not guarantee all the replicas are placed when a file is closed

     [ https://issues.apache.org/jira/browse/HADOOP-1047?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hairong Kuang updated HADOOP-1047:
----------------------------------

    Attachment: testReplication.patch

This patch removes the non-determinism in testReplication by
1. waiting until all replicas are placed
2. allows chooseTarget to ignore the datanode load factor when placing replicas

> TestReplication asserts that the number of replicas that a file has is equal to its replication factor immediately after a file is closed. But DFS only guarantees  the minimun number of replicas is placed when a file is closed. This leads to occasional failure of TestReplication.
