I believe you have a typo in your mapred-site.xml
. You specified:
<name>mapred.job.tracker></name>
^
but
<name>mapred.job.tracker</name>
would be correct. Notice the erroneous >
character before </name>
in your config file.
If this does not help, try https://issues.apache.org/jira/browse/HDFS-2515 and Error in starting hadoop Job Tracker.
