Vinod K V commented on MAPREDUCE-804:
-------------------------------------
split.dta is created by MapTask(non job-setup non job-cleanup) during task
localization in TaskTracker (MapTask.localizeConfiguration()). A search in the
trunk shows that this file is not used anywhere. The split information needed
is serialized everywhere (TaskTracker/Task/Child) and so is available in memory
wherever it is needed. A search in project history split.dta reveals that this
is being added in HADOOP-451, but its original uses no longer seem to be there.
Is the creation of split.dta stale and can it be removed?
If not used anywhere, I am planning to remove it as part of the
DefaultTaskController related changes in HADOOP-4491, making some of the code
changes there a bit clean.
> split.dta is no longer used (?)
