Andrey Klochkov updated HADOOP-8589: ------------------------------------ Attachment: HADOOP-8589.patch Providing an alternative patch: 1. An overloaded implementation of LocalFileSystem is used to a) override the tests root dir as the home dir b) validate that there are no "delete" operations executed out of the tests root dir 2. Just one link is created in the ViewFS mount table, the one for the tests root dir > ViewFs tests fail when tests and home dirs are nested > ----------------------------------------------------- > > Key: HADOOP-8589 > URL: https://issues.apache.org/jira/browse/HADOOP-8589 > Project: Hadoop Common > Issue Type: Bug > Components: fs, test > Affects Versions: 0.23.1, 2.0.0-alpha > Reporter: Andrey Klochkov > Assignee: Andrey Klochkov > Attachments: HADOOP-8589.patch, HADOOP-8859.patch > > > TestFSMainOperationsLocalFileSystem fails in case when the test root > directory is under the user's home directory, and the user's home dir is > deeper than 2 levels from /. This happens with the default 1-node > installation of Jenkins. > This is the failure log: > {code} > org.apache.hadoop.fs.FileAlreadyExistsException: Path /var already exists as > dir; cannot create link here > at org.apache.hadoop.fs.viewfs.InodeTree.createLink(InodeTree.java:244) > at org.apache.hadoop.fs.viewfs.InodeTree.<init>(InodeTree.java:334) > at > org.apache.hadoop.fs.viewfs.ViewFileSystem$1.<init>(ViewFileSystem.java:167) > at > org.apache.hadoop.fs.viewfs.ViewFileSystem.initialize(ViewFileSystem.java:167) > at > org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2094) > at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:79) > at > org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2128) > at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2110) > at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:290) > at > org.apache.hadoop.fs.viewfs.ViewFileSystemTestSetup.setupForViewFileSystem(ViewFileSystemTestSetup.java:76) > at > org.apache.hadoop.fs.viewfs.TestFSMainOperationsLocalFileSystem.setUp(TestFSMainOperationsLocalFileSystem.java:40) > ... > Standard Output > 2012-07-11 22:07:20,239 INFO mortbay.log (Slf4jLog.java:info(67)) - Home dir > base /var/lib > {code} > The reason for the failure is that the code tries to mount links for both > "/var" and "/var/lib", and it fails for the 2nd one as the "/var" is mounted > already. > The fix was provided in HADOOP-8036 but later it was reverted in HADOOP-8129. -- This message is automatically generated by JIRA.
