java - jobtracker.info could only be replicated to 0 nodes, instead of 1 -

hadoop encounter error when starting.the follows log info of jobtracker:

disk space enough, , have closed firewall, result:

[hadooptest@hw009 logs]$ chkconfig iptables --list iptables        0:off   1:off   2:off   3:off   4:off   5:off   6:off 

that's why? how can resolve problem? lots.

there methods have try, couldn't resolve provlem.

enter link1

enter link2

enter link3

i have resolve problem.i used commond bin/start-all.sh start hadoop cluster.but run commond bin/start-dfs.sh firstly, , run commond bin/start-mapred.sh after 5 minutes.

i think maybe server old, start hdfs need long time.when hdfs running, start mapred system not encounter problem.
