> testNegativeCliDriver_stats_aggregator_error_1 fails transiently.
> In one case (not reproducible), it fails consistently. The root-cause is
> ClassNotFoundException for DummyStatsPublisher. please see attachment.
> In the environment, i did a test: move DummyStatsPublisher from src/test to
> src/java and the error is gone. this shows packaging is the issue.
> DummyStatsPublisher is in src/test package. ClassNotFoundException is thrown
> in MR task. This shows it's possible src/test package is not available in
> server side build path in some cases.
> Not sure it is the real and/or only root-cause since it's not always
> reproducible. If all tests pass, feel it's worthy to try.
