Hi,
This is the content of my shell script for running the job history server:
cd $HADOOP_PREFIX
hadoop fs -mkdir -p /mr-history/tmp
hadoop fs -chmod -R 1777 /mr-history/tmp
hadoop fs -mkdir -p /mr-history/done
hadoop fs -chmod -R 1777 /mr-history/done
sbin/mr-jobhistory-daemon.sh start historyserver
These configurable variables are in mapred-site.xml
<property>
<name>mapreduce.jobhistory.address</name>
<value>137.195.143.129:10020</value>
<description>Default port is 10020.</description>
</property>
<property>
<name>mapreduce.jobhistory.webapp.address</name>
<value>137.195.143.129:19888</value>
<description>Default port is 19888.</description>
</property>
I start the history server on the same node as my resource manager
The counters are available from when the job is running from:
http://your-server:8088/proxy/application_1408007466921_0002/mapreduce/job/
job_1408007466921_0002
Drill down through the application master to the job.
If you don¹t have the history server running the job data is not
persistent.
Hope this helps.

Subject: Hadoop 2.2 Built-in Counters
Hi all,
I'm trying to analyze my mapreduce job performance via built-in counters
such as physical memory usage, heap memory usage...
When the job is running, I can watch these counters via Resource manager
website(namenode:8088). However, when the job is done, counter information
is not available in resource manager website anymore. I know I can get
them from client output. I was wondering if there is other place in name
node or data node to get the final counter measures regarding job id?
Thanks,
Shaw
