> Project: Hadoop Common
> Issue Type: Bug
> Components: fs, test
> Affects Versions: 0.23.1, 2.0.0-alpha
> Reporter: Andrey Klochkov

> 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

> 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.
