Thanks Rahman, I have mixed things up a little bit in my mapred-site.xml so
it tried to run the job locally. Now I am running into the problem that
Rahul has, I am unable to to connect to the ResourceManager.
The setup of my targeted cluster runs MR1 instead of YARN, hence the "
mapreduce.framework.name" is set to "classic".
Here are my settings in my mapred-site.xml on the client side.
<property>
<!-- Pointed to the remote JobTracker -->
<name>mapreduce.job.tracker.address</name>
<value>172.31.3.150:8021</value>
</property>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
and my yarn-site.xml
<property>
<description>The hostname of the RM.</description>
<name>yarn.resourcemanager.hostname</name>
<value>172.31.3.150</value>
</property>
<property>
<description>The address of the applications manager interface
in the RM.</description>
<name>yarn.resourcemanager.address</name>
<value>${yarn.resourcemanager.hostname}:8032</value>
</property>
14/04/16 10:23:02 INFO client.RMProxy: Connecting to ResourceManager at /
172.31.3.150:8032
14/04/16 10:23:10 INFO ipc.Client: Retrying connect to server:
hadoop-host1.eng.narus.com/172.31.3.150:8032. Already tried 0 time(s);
retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10,
sleepTime=1 SECONDS)
Therefore, the question is how do I figure out where the ResourceManager is
running?
TIA
Kim
