Subject 0.18.0 DataNode refuses to start...
Date Tue, 26 Aug 2008 04:14:37 GMT
We can get the NameNode and SecondaryNameNode up and running, but DataNodes fail as shown below. 
Hadoop Jira 4019 tracks this problem (https://issues.apache.org/jira/browse/HADOOP-4019),
but I'm curious if anybody has solved it yet...
