TestCheckpoint fails on Windows
-------------------------------
Key: HADOOP-1997
URL: https://issues.apache.org/jira/browse/HADOOP-1997
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.15.0
Environment: Windows
Reporter: Konstantin Shvachko
Assignee: Konstantin Shvachko
Priority: Blocker
The bug is in the test. TestCheckpoint opens edits files in order to verify its
length but does not close it, so the
secondary name-node attempt to delete it (in order to move edits.new into it on
Win) fails.
But this revealed 3 more bugs.
- FSEditLog.purgeEditLog() in case of delete / rename failure calls
FSEditLog.processIOError(), which should have
failed because all FSEditLog streams are closed by that time. It does not
because the condition for throwing the
exception is incorrect.
- In fact purgeEditLog() should call directly FSImage.processIOError() because
again all streams are closed.
- FSImage.processIOError() should also throw an exception if number of
directories is <=1 rather than when it == 1
