---------------------------------------

             Summary: Add a command line tool to read data from all block replicas for a key.
                 Key: HDDS-5739
                 URL: https://issues.apache.org/jira/browse/HDDS-5739
             Project: Apache Ozone
          Issue Type: Task
          Components: Ozone Client, Ozone Datanode
            Reporter: Aravindan Vijayan
             Fix For: 1.3.0


To help triage data corruption issues better, it would be good to have a CLI tool that attempts to read data from all block replicas and downloads copies of the file along with information on which file consists of which block replicas. This would help us understand which replica(s) is(are) problematic.

Since keys can contain multiple blocks, we need to come with a mechanism of choosing a unique set of block replicas to construct a file as possible. When the implementation details are fully hashed out in this task, description will be updated.
