[jira] [Commented] (CASSANDRA-14791) [utest] tests unable to write
system tmp directory
[ https://issues.apache.org/jira/browse/CASSANDRA-14791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16641314#comment-16641314 ]
Jay Zhuang commented on CASSANDRA-14791:
----------------------------------------
The root cause of this test failure is not because {{/tmp/}} directory is not writable. But because the unittest generated tmp files {{/tmp/na-1-big-Data.db}} and {{/tmp/na-1-big-CompressionInfo.db}} are not deleted after the test. So I guess on these nodes, the test was run by other user, which left the tmp files that the current user cannot override. I'm able to reproduce the same error message by:
{noformat}
sudo chown root:root /tmp/na-1-big-Data.db
{noformat}
Here is a patch for trunk:
| Branch | uTest |
| [14791|https://github.com/cooldoger/cassandra/tree/14791] | [!https://circleci.com/gh/cooldoger/cassandra/tree/14791.svg?style=svg!|https://circleci.com/gh/cooldoger/cassandra/tree/14791] |
Passed the tests in Jenkins:
