> On my Ubuntu / x86_64 machine, configured for Hadoop since months, I've run Hadoop tests
of branch branch-2.7 (source code of Monday May 26th) during days. It produced 14 runs in
the EXACT same environment. And it shows that several tests sometimes fail, randomly.
> 12 runs gave the exact same number of tests done and tests skipped:
>     - 10977 tests
>     -     254 skipped
> 1 test gave only 10972 tests. Another gave only 9760 tests.
> I've used the 12 runs with 10977 tests for building the attached result file, which shows
that 33 tests sometimes fail.
> T: Tests
> F: Failures
> E: Errors
> S: Skipped
> NN/n : Number of times the issue appeared out of the 12 runs
> m-M: minimum number of failure up to Maximum number of failures.
> Example:
>                                                                   T      F      E
