Subject accessing hadoop job history
Date Sat, 20 Jun 2015 19:09:34 GMT
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)
    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70)
    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84)
    at org.apache.hadoop.mapred.JobClient.main(JobClient.java:1237)
    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
