             Summary: EC: Bucket create replication help text is incorrect
                 Key: HDDS-6232
                 URL: https://issues.apache.org/jira/browse/HDDS-6232
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: Ozone CLI
            Reporter: Stephen O'Donnell


The help for the "ozone sh bucket create" command does not align with the validation:


{code:java}
$ ozone sh bucket create -h         
Usage: ozone sh bucket create [-ghV] [-k=<bekName>] [-l=<allowedBucketLayout>]
                              [--namespace-quota=<quotaInNamespace>]
                              [--quota=<quotaInBytes>] [-r=<replication>]
                              [-t=<replicationType>] [-u=<ownerName>] <value>
creates a bucket in a given volume
      <value>              URI of the volume/bucket.
                           Ozone URI could start with o3:// or without prefix.
                             URI may contain the host/serviceId and port of the
                             OM server. Both are optional. If they are not
                             specified it will be identified from the config
                             files.
  -g, --enforcegdpr        if true, indicates GDPR enforced bucket,
                             false/unspecified indicates otherwise
  -h, --help               Show this help message and exit.
  -k, --bucketkey=<bekName>
                           bucket encryption key name
  -l, --layout=<allowedBucketLayout>
                           Allowed Bucket Layouts: FILE_SYSTEM_OPTIMIZED,
                             OBJECT_STORE
      --namespace-quota=<quotaInNamespace>
                           For volume this parameter represents the number of
                             buckets, and for buckets represents the number of
                             keys (eg. 5)
      --quota, --space-quota=<quotaInBytes>
                           The maximum space quota can be used (eg. 1GB)
  -r, --replication=<replication>
                           Replication value. Example: 3 (for Ratis type) or 1
                             ( for standalone type). In the case of EC, pass
                             DATA-PARITY, eg 3-2, 6-3, 10-4
  -t, --type=<replicationType>
                           Replication type. Supported types are RATIS,
                             STANDALONE, EC
  -u, --user=<ownerName>   Owner of the bucket. Defaults to current user if not
                             specified
  -V, --version            Print version information and exit.
bash-4.2$ ozone sh bucket create -t EC -r 3-2 /vol1/ec
EC replication config should be defined in the form rs-3-2-1024k, rs-6-3-1024; or rs-10-4-1024k.Provided configuration was: 3-2{code}
Note it says "In the case of EC, pass DATA-PARITY, eg 3-2, 6-3, 10-4"

However passing that gives an error. You need to pass "rs-3-2-1024k".

We need to either fix the help text, or make the validation more flexible to default to RS and 1024k if they are not in the string.

There is also a missing space in the error:

"... or rs-10-4-1024k.Provided configuration was: 3-2"
