> Flaky test: testViewFsMultipleExportPoint may encounter race condition which
> leads to namenode ID collisions
> ------------------------------------------------------------------------------------------------------------
>
> Key: HDFS-17844
> URL: https://issues.apache.org/jira/browse/HDFS-17844
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode, test
> Reporter: Yakun Wang
> Priority: Major
> Labels: patch, pull-request-available
>
> There could be a race condition in namenode ID generation, causing ID
> collisions. However, the underlying collision detection logic is incorrect
> because it throws an error as long as the namenode ID exists, even if the URI
> is the same. Same namenode ID with same URI is safe. What needs to be
> detected is that different URIs resolve to the same namenode ID, which is a
> security problem.
> Error output:
> `[ERROR] Errors:
> [ERROR] TestExportsTable.testViewFsMultipleExportPoint:111 ยป FileSystem
> FS:viewfs, Namenode ID collision for path:/hdfs2 nnid:2130740544 uri being
> added:hdfs://localhost:34111/ existing uri:hdfs://localhost:34111/`
> Functions that are related to collision detection logic:
