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!
2010-09-17 17:07:22,863 FATAL org.apache.hadoop.mapred.JobTracker:
java.net.BindException: Problem binding to hostname/ipaddress:45365 :
Cannot assign requested address
Configure in mapred-site.xml:
<property>
<name>mapred.job.tracker</name>
<value>hostname:45365</value>
</property>
Best,

Some suggestions:
1) try:
<property>
<name>mapred.job.tracker</name>
<value>hdfs://hostname:45365</value>
</property>
2) Is the port correct?
3) Is the hostname correct?
4) Have you verfified that the host is definitely listening on that
port? (e.g., netstat -nap | grep LISTEN)
