Regis Xu resolved HARMONY-6675.
-------------------------------

       Resolution: Fixed
    Fix Version/s: 5.0M16

Thanks Guillermo.

I just committed a patch that could configure timeout via system property 'org.apache.harmony.file.canonical.path.cache.timeout' and reduce default timeout value to 30 seconds.
The revision is r1035930, please check if it could resolve your problem.

> Testing Harmony Select (r1022137) with Hadoop common, we ran across the following error:
> java.lang.RuntimeException: Error while running command to get file permissions : org.apache.hadoop.util.Shell$ExitCodeException: /bin/ls: /tmp/test1/file: No such file or directory
> Charles Lee (Apache Harmony developer) provided us with the following answer:
> "For all the test case failures in org.apache.hadoop.fs.TestLocalFSFileContextSymlink, the root cause is we have a CanonicalPathCache under the File, so the file canonical path will be wrong if the test case highly stressed, (I remember the cache time is set to 10 minute)."
> His patch to fix this issue has been attached.
