/**
 * 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.
 * <p>
 * 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.
