Subject [jira] [Updated] (ACCUMULO-3925) Remove unnecessary warning messages from FATE ops
Date Mon, 29 Jun 2015 20:18:04 GMT


Josh Elser updated ACCUMULO-3925:
    Attachment: ACCUMULO-3925.2.patch

Makes AcceptableException an interface in fate/ and makes an AcceptableThriftTableOperationException
that the FATE ops throw. The Fate class can then key off of the AcceptableException class
and choose the level to log at.

Better solution over the previous because the thrown AcceptableThriftTableOperationException
is still a ThriftTableOperationException and requires less code elsewhere.

They are perfectly normal and expected. We should not be putting a warning to the monitor
for this messages. The exception thrown back to the client is sufficient.
