TestInjectionForSimulatedStorage only works on a clean directory structure
--------------------------------------------------------------------------
Key: HADOOP-3900
URL: https://issues.apache.org/jira/browse/HADOOP-3900
Project: Hadoop Core
Issue Type: Bug
Components: test
Reporter: Steve Loughran
I've been getting intermittent failures on
org.apache.hadoop.hdfs.TestInjectionForSimulatedStorage
Timedout while waiting for all blocks to be replicated for
/replication-test-file
java.io.IOException: Timedout while waiting for all blocks to be replicated for
/replication-test-file

at
org.apache.hadoop.hdfs.TestInjectionForSimulatedStorage.testInjection(TestInjectionForSimulatedStorage.java:151)
Here's how to replicate it: run the test twice.
When run the second time, the trace is full of log messages like :

Am I the only person seeing this?
