Subject Re: hadoop multinode, only master node doing the work
Date Sun, 13 Jul 2014 19:47:04 GMT
Hi, Ravi:

Thanks again for your help!

The website only shows one node. a screenshot is attached.

I restart the service, on master, it says:
xisisu@master:/usr/local/hadoop$ jps
15862 Jps
15570 NodeManager
15461 ResourceManager
15149 DataNode
15025 NameNode

on slave, it says:
xisisu@slave-01:/usr/local/hadoop$ jps
19752 DataNode
19859 NodeManager
20003 Jps

I also checked the yarn log on the slave node, seems it cannot connect to
the server,
xisisu@slave-01:/usr/local/hadoop$ tail
logs/yarn-xisisu-nodemanager-slave-01.log

I googled and found this:
http://hortonworks.com/community/forums/topic/retrying-connect-to-server-0-0-0-00-0-0-08030/

Seems it is the configuration error?

Thanks very much!
