----------------------------------------
Summary: Avoid making separate RPC calls for FileStatus and block
locations in FileInputFormat
Key: MAPREDUCE-7016
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7016
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Chris Douglas
{{FileInputFormat::getSplits}} uses {{FileSystem::globStatus}} to determine its
inputs. When the glob returns directories, each is traversed and
{{LocatedFileStatus}} instances are returned with the block locations. However,
when the glob returns files, each requires a second RPC to obtain its locations.
