-----------------------------------
Summary: proposal for developing a tool to compare files/dirs
Key: HDFS-6491
URL: https://issues.apache.org/jira/browse/HDFS-6491
Project: Hadoop HDFS
Issue Type: New Feature
Components: tools
Affects Versions: 2.4.0
Reporter: Yongjun Zhang
Assignee: Yongjun Zhang
We have a tool distcp that copy files similar to unix/linux cp command but copy
files in a distributed way, but we don't have a tool to compare files/dirs. I
think to provide such a tool like this would be helpful. We can name it
distdiff to be consistent with distcp.
Right now I'm thinking about providing some basic functionality as a starting
point, and we can add more features or add performance improvement later.
I had opportunity to discuss this with [~daryn] and [~szetszwo] in person.
Thanks both of them a lot for the very valuable inputs.
