             Summary: Fix error handling in KeyValueContainerCheck
                 Key: HDDS-1365
                 URL: https://issues.apache.org/jira/browse/HDDS-1365
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
          Components: Ozone Datanode
            Reporter: Supratim Deka
            Assignee: Supratim Deka


Error handling and propagation in KeyValueContainerCheck needs to be based on throwing IOException instead of passing an error code to the calling function.

HDDS-1163 implemented the basic framework using a mix of error code return and exception handling. There is added complexity because exceptions deep inside the call chain are being caught and translated to error code return values. The goal is to change all error handling in this class to use Exceptions.
