Subject Re: using "-libjars" in Hadoop 2.2.1
Date Wed, 16 Apr 2014 17:31:43 GMT
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
