[jira] Created: (HADOOP-1106) Number of DataNodes less than target
replication causes NameNode WARN message every millisecond
Number of DataNodes less than target replication causes NameNode WARN message every millisecond
-----------------------------------------------------------------------------------------------
Key: HADOOP-1106
URL: https://issues.apache.org/jira/browse/HADOOP-1106
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.12.0
Reporter: Nigel Daley
Fix For: 0.13.0
When I startup a 4 DataNode cluster that already contains files with a target replication of 3, but 2 of the DataNodes fail to come online (ie. there are fewer DataNodes then the target replication), I get the following output in the NameNode log every millisecond or less, continued forever:
2007-03-09 22:45:22,848 WARN org.apache.hadoop.fs.FSNamesystem: Not able to place enough replicas, still in need of 2

Hairong Kuang commented on HADOOP-1106:
---------------------------------------
I created a file with a replication factor of 3 on a 2-node dfs cluster, but was not able to reproduce the error. Nigel, could you please check if I miss anything?
