> .TestFiDataTransferProtocol2#pipeline_Fi_18 sometimes fails with the
> following error:
> junit.framework.AssertionFailedError:
> at
> org.apache.hadoop.hdfs.server.datanode.TestFiDataTransferProtocol2.runTest17_19(TestFiDataTransferProtocol2.java:139)
> at
> org.apache.hadoop.hdfs.server.datanode.TestFiDataTransferProtocol2.pipeline_Fi_18(TestFiDataTransferProtocol2.java:186)
> Which means that the test did not trigger pipeline recovery. The test log
> shows that there is no fault injected to the pipeline. It turns out there is
> a bug in the test code. Counting down 3 means inject a fault when receiving
> the fourth packet. But the code allows the file to have only 3 packets.
