.TestFiDataTransferProtocol2#pipeline_Fi_18 sometimes fails
-----------------------------------------------------------
Key: HDFS-849
URL: https://issues.apache.org/jira/browse/HDFS-849
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 0.20.1
Reporter: Hairong Kuang
Assignee: Hairong Kuang
Fix For: 0.21.0, 0.22.0
.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.
