------------------------------------

             Summary: data type of parameter 'mapreduce.task.exit.timeout' is inconsistent
                 Key: MAPREDUCE-7299
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7299
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: leafeonia


*Problem:*

The data type of parameter `mapreduce.task.exit.timeout` is inconsistent in the code relevant to the parameter.

In `TaskAttemptFinishingMonitor.java`, getInt() is used to load the parameter value:
{code:java}
int expireIntvl = conf.getInt(MRJobConfig.TASK_EXIT_TIMEOUT,
  MRJobConfig.TASK_EXIT_TIMEOUT_DEFAULT);{code}
However, in `TaskHeartbeatHandler.java`, the code uses getLong() instead and stores the value in a long-type variable.
{code:java}
private long unregisterTimeOut;
...
unregisterTimeOut = conf.getLong(MRJobConfig.TASK_EXIT_TIMEOUT,
  MRJobConfig.TASK_EXIT_TIMEOUT_DEFAULT);{code}
 

*Solution:*

Convert the type explicitly to avoid inconsistency and potential problems:
{code:java}
unregisterTimeOut = (long)conf.getInt(MRJobConfig.TASK_EXIT_TIMEOUT, 
  MRJobConfig.TASK_EXIT_TIMEOUT_DEFAULT);{code}
