Hadoop jobtracker's tracking url cannot access - hadoop

Question

I have configured my hadoop system in wsl and run the wordcount example. But when I want to see the history of the job, I found the tracking url cannot access.
The job is working well, the jobhistory is running as well.
The history tracking url is my wsl hostname:8088/proxy/application_1585482453915_0002/.
You can see the url above.
But I can still access to localhost:19888/jobhistory to see my jobhistory.
How is this problem occurs? Is it a problem of configuration?
My hadoop version is 2.7.1.

Answer 1

The JobHistoryServer daemon is running in localhost (127.0.0.1), whereas the tracking URL is constructed with the hostname, thus redirecting to DESKTOP-U1EOV4J.localdomain (127.0.1.1).
For a Pseudo distributed cluster, it is safer to leave the host of JobHistoryServer to be 0.0.0.0.
Update the job history server properties in mapred-site.xml
<property>
<name>mapreduce.jobhistory.address</name>
<value>0.0.0.0:10020</value>
</property>
<property>
<name>mapreduce.jobhistory.webapp.address</name>
<value>0.0.0.0:19888</value>
</property>
and restart the JobHistoryServer.
