Ashutosh Chauhan commented on HIVE-3971:
----------------------------------------
I am not sure if this indeed is the root cause, because this is deterministic
cause and the test cause would have always failed, not randomly. Further if
this was the reason, test case itself would only fail, but currently it doesn't
fail but causes the crash of TestNegativeCliDriver.

> 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.
