> 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
> Priority: Minor
> Attachments: MAPREDUCE-7299-001.patch
>
>
> *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}
