Steve Loughran commented on YARN-4928:
--------------------------------------
an absolute {{/tmp}} path is "probably" mapped into a path on the current
drive, e.g. {{c:\tmp}} . (Trivia: every drive on a windows system has its own
current directory).
> Some yarn.server.timeline.* tests fail on Windows attempting to use a test
> root path containing a colon

> Key: YARN-4928
> URL: https://issues.apache.org/jira/browse/YARN-4928
> Project: Hadoop YARN
> Issue Type: Bug
> Components: test
> Affects Versions: 2.8.0
> Environment: OS: Windows Server 2012
> JDK: 1.7.0_79
> Reporter: Gergely Novák
> Assignee: Gergely Novák
> Priority: Minor
> Attachments: YARN-4928.001.patch

>
> yarn.server.timeline.TestEntityGroupFSTimelineStore.* and
> yarn.server.timeline.TestLogInfo.* fail on Windows, because they are
> attempting to use a test root paths like
> "/C:/hdp/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-timeline-pluginstorage/target/test-dir/TestLogInfo",
> which contains a ":" (after the Windows drive letter) and
> DFSUtil.isValidName() does not accept paths containing ":".
> This problem is identical to HDFS-6189, so I suggest to use the same
> approach: using "/tmp/..." as test root dir instead of
> System.getProperty("test.build.data", System.getProperty("java.io.tmpdir")).
