Ewan Higgs created HDFS-13580:
---------------------------------
Summary: FailOnTimeout error in
TestDataNodeVolumeFailure$testVolumeFailure
Key: HDFS-13580
URL: https://issues.apache.org/jira/browse/HDFS-13580
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Ewan Higgs
testVolumeFailure is flaky. If we run it 50 times, it will fail about twice
with the following backtrace:
{code:java}
java.lang.Exception: test timed out after 120000 milliseconds
at java.lang.Object.wait(Native Method)
at java.lang.Thread.join(Thread.java:1253)
at
org.junit.internal.runners.statements.FailOnTimeout.evaluateStatement(FailOnTimeout.java:26)

org.junit.internal.runners.statements.FailOnTimeout.evaluate(FailOnTimeout.java:17)

org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27)
at
org.junit.internal.runners.statements.FailOnTimeout$StatementThread.run(FailOnTimeout.java:74){code}
The second error (immediately after) is probably due to an issue with cleaning
up a timed out test:
{code:java}
