> Distcp parallel file copy breaks the modification time
> ------------------------------------------------------

> Key: HADOOP-17611
> URL: https://issues.apache.org/jira/browse/HADOOP-17611
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Adam Maroti
> Assignee: Adam Maroti
> Priority: Major
> Labels: pull-request-available
> Time Spent: 2h 50m

> The commit HADOOP-11794. Enable distcp to copy blocks in parallel.
> (bf3fb585aaf2b179836e139c041fc87920a3c886) broke the modification time of
> large files.
>
> In CopyCommitter.java inside concatFileChunks Filesystem.concat is called
> which changes the modification time therefore the modification times of files
> copeid by distcp will not match the source files. However this only occurs
> for large enough files, which are copied by splitting them up by distcp.
> In concatFileChunks before calling concat extract the modification time and
> apply that to the concatenated result-file after the concat. (probably best
> -after- before the rename()).
