> Key: HDDS-9182
> URL: https://issues.apache.org/jira/browse/HDDS-9182
> Project: Apache Ozone
> Issue Type: Task
> Components: Ozone CLI
> Reporter: Pratyush Bhatt
> Priority: Major
>
> In HDFS, for leaseRecovery CLI we have the option to retry using -retries parameter:
> {noformat}
> hdfs debug recoverLease
> recoverLease -path <path> [-retries <num-retries>]
> Recover the lease on the specified path. The path must reside on an
> HDFS filesystem. The default number of retries is 1.{noformat}
> How it works:
> {noformat}
> hdfs debug recoverLease -path /tmp/zdu_1692200498/File.txt -retries 3

> We should have something similar for ozone, currently in ozone we dont have the -retries option for leaseRecovery.
> {noformat}
> ozone debug recover
> Missing required option: '--path=<path>'
> Usage: ozone debug recover --path=<path>
> recover the lease of a specified file. Make sure to specify file system scheme
> if ofs:// is not the default.
> --path=<path> Path to the file{noformat}
