Hello , Can you check the
<name>dfs.http.address</name> <value>50004</value> in hadoop-site.xml due to which it is not able to identify the host:port pair address. 2008-03-11 11:47:08,370 ERROR org.apache.hadoop.dfs.NameNode: java.lang.RuntimeException: Not a host:port pair: 50004 So either don't specify in hadoop-site.xml , use default one available in hadoop-default.xml .
