------------------------------------
Summary: StripedFileTestUtil#readAll flaky
Key: HDFS-10293
URL: https://issues.apache.org/jira/browse/HDFS-10293
Project: Hadoop HDFS
Issue Type: Bug
Components: erasure-coding, test
Affects Versions: 3.0.0
Reporter: Mingliang Liu
Assignee: Mingliang Liu
The flaky test helper method cause several UT test failing intermittently. For
example, the
{{TestDFSStripedOutputStreamWithFailure#testAddBlockWhenNoSufficientParityNumOfNodes}}
timed out in a recent run (see
[exception|https://builds.apache.org/job/PreCommit-HDFS-Build/15158/testReport/org.apache.hadoop.hdfs/TestDFSStripedOutputStreamWithFailure/testAddBlockWhenNoSufficientParityNumOfNodes/]),
which can be easily reproduced locally.
Debugging at the code, chances are that the helper method is stuck in an
infinite loop. We need a fix to make the test robust.
