Subject [jira] Created: (HADOOP-1052) Map tasks not getting killed
Date Wed, 28 Feb 2007 21:49:50 GMT
Map tasks not getting killed
----------------------------

                 Key: HADOOP-1052
                 URL: https://issues.apache.org/jira/browse/HADOOP-1052
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.11.2
         Environment: Redhat, 8 node cluster
            Reporter: Srikanth Kakani


-----------Steps to reproduce---------

1. Create and compile a map reduce application with 
public void map(WritableComparable key,
                    Writable value,
                    OutputCollector output, Reporter reporter) throws IOException {

     reporter.setStatus("Started");
    Thread.sleep(3600000);
    report.setStatus("Should have been killed"); 

}

2. Run the task with the default hadoop configuration: 

<property>
  <name>mapred.task.timeout</name>
  <value>1200000</value>
  <description>The number of milliseconds before a task will be
  terminated if it neither reads an input, writes an output, nor
  updates its status string.
  </description>
</property>

----------------Result------------------
The task does not get killed, and the job is successful

----------------Expected Result------------------
The map tasks get killed and the job should fail.
