Key: HADOOP-4871
URL: https://issues.apache.org/jira/browse/HADOOP-4871
Project: Hadoop Core
Issue Type: Task
Affects Versions: 0.17.1
Environment: Ubuntu 8.04
Reporter: Dino M. Amaral
I got 3 hosts in the cluster : one for master 172.18.30.149 and the others as
slaves (172.18.30.137 e 172.18.30.153). When i try to start, i got the
following error. When i configure the masters file, and try 172.18.30.137, the
secondary namenode starts.
I think the problem is at master (172.18.30.149), cause this host doesn´t start
neither Namenode nor secondary NameNode.
Cloud anyone give me a hand ????
