Interface AcceptableException

All Known Implementing Classes:

AcceptableThriftTableOperationException

public interface AcceptableException

An exception for FATE operations to use to denote when an Exception is acceptable and should not trigger warning messages. This exception is intended to wrap an existing exception from a FATE op implementation so that the FATE runner can know that the exception doesn't need to warn.

Often times, problems that map well into the FATE execution model have states in which it is impossible to know ahead of time if an exception will be thrown. For example, with concurrent create table operations, one of the operations will fail because the table already exists, but this is not an error condition for the system. It is normal and expected.
