Subject [jira] [Updated] (HADOOP-11984) Enable parallel JUnit tests in pre-commit.
Date Tue, 26 May 2015 19:07:20 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11984?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Nauroth updated HADOOP-11984:
    Attachment: HADOOP-11984.011.patch

Even when {{TestCredentials}} runs in isolation, the parent directory isn't there, so that
rules out another concurrent test interfering.  This is very strange.  Is something going
wrong with the mkdir of the test directories inside pom.xml?  I wouldn't expect so, because
we'd see error output and an earlier failure in the build.

The fix might be just to change {{TestCredentials}} to use a recursive {{mkdirs}}, which is
what other tests do.  I'm really curious about this though, so patch v011 is one more troubleshooting
patch that echoes the directories that pom.xml tries to create.  Let's see if these are any
different from what I see on my local machine.

> HADOOP-9287 and related issues implemented the parallel-tests Maven profile for running
JUnit tests in multiple concurrent processes.  This issue proposes to activate that profile
during pre-commit to speed up execution.
