---------------------------------------
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.
