--------------------------------------
Summary: In DistCp, prevent unnecessary getFileStatus call when
not preserving metadata.
Key: HADOOP-13145
URL: https://issues.apache.org/jira/browse/HADOOP-13145
Project: Hadoop Common
Issue Type: Improvement
Components: tools/distcp
Reporter: Chris Nauroth
Assignee: Chris Nauroth
After DistCp copies a file, it calls {{getFileStatus}} to get the
{{FileStatus}} from the destination so that it can compare to the source and
update metadata if necessary. If the DistCp command was run without the option
to preserve metadata attributes, then this additional {{getFileStatus}} call is
wasteful.
