Research direction
Start by running GetBlobOperationTest.testDataChunkFailure[1] and review the stack-trace locations in GetBlobOperationTest.java:222, 557, and 862. Trace why the data-chunk failure reaches an UnexpectedInternalError with a success target larger than the replica count. Done means the intermittent Travis failure is resolved and the test passes without that exception.
