------------------------------------------
Currently, we have `ozone admin container list` command which gives a list of
containers. We can then use `ozone admin container info <id>` command to get
the replica details. Sample output:
{code:java}
# ozone admin container info 1001
Container id: 1001
Pipeline id: e933fd02-5ea0-43e2-881a-040ee2042a6a
Container State: OPEN

Comparing with hdfs fsck, the portion of information not present in the
commands is container to key mapping. But this can also be found with using a
recon endpoint `/api/v1/container/:id/keys`. (See
[https://ozone.apache.org/docs/current/interface/swaggerreconapi.html#/Containers%20and%20Keys/getKeysForContainer]
for more information)
We can do any of the following, depending on what the requirement is:
1. Create a command to consolidate information from the recon endpoint
`/api/v1/container/:id/keys` and `ozone admin container info` command, to get
output similar to `hdfs fsck -blockID`
2. We have blocks inside containers. We could have mapping from block to key
and introduce another recon API to do that.
3. Have a tool to iterate over keys from OM and check if blocks for the keys
are present, perform some validations and report inconsistencies just like hdfs
fsck.
[~nakumar] could you please check regarding the above points and see what the
requirement is?

> Project: Apache Ozone
> Issue Type: New Feature
> Components: Ozone CLI
> Reporter: Navin Kumar
> Assignee: Tejaskriya Madhan
> Priority: Major
>
> ➤ Need Something similar to hdfs fsck for Ozone CLI where using single
> command we can fetch all three container information for the pipeline.
> * We can get the list of container using ozone admin commands and container
> info under scm.db by using ozone debug ldb commands . But unfortunately we do
> not have such utility in ozone like fsck in hdfs where we can get container
> pipeline info .
