[jira] [Created] (MAPREDUCE-6099) Adding getSplits(JobContext job,
List stats) to mapreduce CombineFileInputFormat
Pankit Thapar created MAPREDUCE-6099:
----------------------------------------
Summary: Adding getSplits(JobContext job, List<FileStatus> stats) to mapreduce CombineFileInputFormat
Key: MAPREDUCE-6099
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6099
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: client
Affects Versions: 2.4.1
Reporter: Pankit Thapar
Priority: Critical
Fix For: 2.4.1
Currently we have getSplits(JobContext job) in CombineFileInputFormat.
This api does not give freedom to the client to create a list if file status it self and then create splits on the resultant List<FileStatus> stats.
The client might be able to perform some filtering on its end on the File sets in the input paths. For the reasons, above it would be a good idea to have getSplits(JobContext, List<FileStatus>).
Please let me know what you think about this.
