Have you considered configuring the JT with a hostname other than

Many thanks in advance!

Dear all,

I am having this exception when starting jobtracker, and I checked by
netstat that the port is not in use before running. Could you please
point out where might be the problem? Many thanks in advance!

Configure in mapred-site.xml:

    <value>hostname:45365</value>
</property>
