Mapreduce Example Fails about spring-hadoop-samples

[trisberg]

Could you try setting this property in your config:

yarn.resourcemanager.hostname

Set that to the hostname where the RM is running.

Yep, that was it. Thanks!

Is there any guidance from the Spring Hadoop team on the best way to ensure all the properties are correct? For example, would it make sense to copy a yarn-site.xm and mapred-site.xml to the client machine and pull it into the spring config? Or could that cause other types of problems?

I've used both ways for providing config options and the net effect is the same, so pick the one that you are more comfortable using. I tend to prefer to collect my configurations in a properties file that's part of my application.

Hi, Same problem...but coudnt solve....please help...i have a 5 node cluster with one master and 4 slaves.
I have set the ip-address of the master node [in fact even tried hard-coding] for 'yarn.resourcemanager.hostname' in the yarn-site.xml file. But even then i get the following in the log files.
ERROR:........Configuration: job.xml:an attempt to override final parameter: mapreduce.job.end-notification.max.retry.interval; Ignoring.
2014-03-05 20:15:50,597 WARN [main] org.apache.hadoop.conf.Configuration: job.xml:an attempt to override final parameter: mapreduce.job.end-notification.max.attempts; Ignoring.

What could be the reason. Why is not hadoop picking up the parameter that i had set...???
