Spark/Hadoop workloads which use Hadoop MR Committer v1/v2 algorithm upload objects to a temporary prefix in a bucket. These objects are 'renamed' to a different prefix on Job commit. Object storage admins are forced to configure separate ILM policies to expire these objects and their versions to reclaim space.

    @MethodSource("wrapExceptions")
    void connectWrapException_wrapsToSmbException(SmbResourceLocatorImpl loc, Exception thrown) throws Exception {
        // Arrange: spy on instance to force connect() failure with specific exception
        CIFSContext ctx = mock(CIFSContext.class);
        SmbTreeConnectionTrace trace = Mockito.spy(new SmbTreeConnectionTrace(ctx));
        doThrow(thrown).when(trace).connect(loc);
