leafeonia created MAPREDUCE-7299:
------------------------------------
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}
