Subject [jira] [Updated] (HDDS-560) Create Generic exception class to be used by S3 rest services
Date Tue, 02 Oct 2018 14:11:00 GMT

     [ https://issues.apache.org/jira/browse/HDDS-560?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Elek, Marton updated HDDS-560:
    Resolution: Fixed
        Status: Resolved  (was: Patch Available)


I agree with [~anu] that we need to clean up the exception handling for the OzoneClient. It's
very bad that we need to check the exception message to identify NOT_FOUND problems.

Still I am not convinced that we need a checked exception, but as I wrote it's more like a
personal taste.

I just committed this to trunk. (We can do further improvements when we need. For example
when we will have more specific OzoneClient exceptions)

Thank you [~bharatviswa] the contribution.
