Brandon Williams created CASSANDRA-6983:
-------------------------------------------
Summary: DirectoriesTest fails when run as root
Key: CASSANDRA-6983
URL: https://issues.apache.org/jira/browse/CASSANDRA-6983
Project: Cassandra
Issue Type: Bug
Components: Tests
Reporter: Brandon Williams
Assignee: Yuki Morishita
Fix For: 2.0.7
When you run the DirectoriesTest as a normal user, it passes because it fails
to create the 'bad' directory:
{noformat}
[junit] ------------- Standard Error -----------------
[junit] ERROR 16:16:18,111 Failed to create
/tmp/cassandra4119802552776680052unittest/ks/bad directory
[junit] WARN 16:16:18,112 Blacklisting
/tmp/cassandra4119802552776680052unittest/ks/bad for writes
[junit] ------------- ---------------- ---------------
{noformat}
But when you run the test as root, it succeeds in making the directory, causing
an assertion failure that it's unwritable:
{noformat}
[junit] Testcase:
testDiskFailurePolicy_best_effort(org.apache.cassandra.db.DirectoriesTest):
FAILED
[junit]
[junit] junit.framework.AssertionFailedError:
[junit] at
org.apache.cassandra.db.DirectoriesTest.testDiskFailurePolicy_best_effort(DirectoriesTest.java:199)
{noformat}
It seems to me that we shouldn't be relying on failing the make the directory.
If we're just going to test a nonexistent dir, why try to make one at all? And
if that is supposed to succeed, then we have a problem with either the test or
blacklisting.
