> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 0.20.2
> Reporter: Suresh Antony
> Priority: Minor
> Labels: distcp
> Fix For: 0.20.2

> Attachments: HADOOP-8065-trunk_2015-11-03.patch, patch.distcp.2012-02-10

>
> We would like compress the data while transferring from our source system to target system. One way to do this is to write a map/reduce job to compress that after/before being transferred. This looks inefficient.
> Since distcp already reading writing data it would be better if it can accomplish while doing this.
> Flip side of this is that distcp -update option can not check file size before copying data. It can only check for the existence of file.
> So I propose if -compress option is given then file size is not checked.
> Also when we copy file appropriate extension needs to be added to file depending on compression type.
