Jobtracker could only be replicated to 0 nodes instead of 1
Hello friends,
I got the above error "jobtarcker.info could only be replicated to 0 nodes
instead of 1 "
Tried different Solutions found on web :
* Formatted namenode
* removed tmp Folder
* cleaned uncessary logs just to have more space
But still no success . What other Solutions could it be ?
your advices would be appreciated.Thank you.
Regards,
shosaman

I had the same issue. Can you try disabling firewall from both datanode and resourcemanager using "sudo /etc/init.d/iptables stop"?

When i checked hadoop dfsadmin -report
then i could see 1 datanode is up .so i assume datanode is working .
Also i see all the 5 daemons running when i run jps command.
The only error i saw is in nam node logs is that job tracker.info could only be replicated to 0 nodes instead of 1 .
Rest in other logs i found no error just some warnings EOF exception. Just attached logs for reference. Please point me what should be corrected.

you have set replication factor to 1, I am assuming its running a single
node cluster.
i would recommend you to check the datanode logs to see if it was able to
connect with namenode successfully.
