Thank you! I'm a fresh man in Hadoop Community. Thank you for your direction.

I'm writing some testCase for Hadoop-HDFS and find this by chance. This is a very uncommon
case.But similiar events affect other TestCase I designed in boundary testing for HDFS.

> When run a given test case for Banlancer Test. In the test the banlancer thread try to
move some block cross the rack but it can't find any available blocks in the source rack.
Then the thread won't interrupt until the tag isTimeUp reaches 20min. But maven judges the
test failed because the thread have runned for 15min.
