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 fails because DFS does not guarantee all the replicas are
> placed when a file is closed
> ------------------------------------------------------------------------------------------------------

> Key: HADOOP-1047
> URL: https://issues.apache.org/jira/browse/HADOOP-1047
> Project: Hadoop
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.11.2
> Reporter: Hairong Kuang
> Assigned To: Hairong Kuang
> Attachments: testReplication.patch
>
>
> 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.
