Answer 1

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.
