accessing hadoop job history

Sat, 20 Jun 2015 12:10:07 -0700 

Hi,

I ma new to Hadoop and when I run

    hadoop job -history output

I get this

    Ignore unrecognized file: output
    Exception in thread "main" java.io.IOException: Unable to initialize
History Viewer
    at
org.apache.hadoop.mapreduce.jobhistory.HistoryViewer.<init>(HistoryViewer.java:90)
    at org.apache.hadoop.mapreduce.tools.CLI.viewHistory(CLI.java:487)
    at org.apache.hadoop.mapreduce.tools.CLI.run(CLI.java:330)

    Caused by: java.io.IOException: Unable to initialize History Viewer
    at
org.apache.hadoop.mapreduce.jobhistory.HistoryViewer.<init>(HistoryViewer.java:84)
    ... 5 more


I checked the logs (history server logs,
`mapred-*username*-historyserver-**.local.log` ), and there are empty. How
can I solve it ?

Best regards,
Mehdi
