Tsuyoshi Ozawa commented on HADOOP-12589:
-----------------------------------------

[~cnauroth] thank you for taking a look. Currently, does one Jenkins server run 
on same machine or run tests in parallel? If so, we can switch off the parallel 
test execution or we can fix the test to handle the failure of mkdir.
