Description

Recently ASF License warnings generated intermittently in trunk.

Lines that start with ????? in the ASF License  report indicate files that do not have an Apache license header:
 !????? /testptch/hadoop/hadoop-hdfs-project/hadoop-hdfs/include-hosts-file
 !????? /testptch/hadoop/hadoop-hdfs-project/hadoop-hdfs/exclude-hosts-file

The root cause of this is that the include/exclude host file created in a wrong place in test TestBalacner. It's expected in a right test directory. When some unit tests ran timeout in TestBalacner, then these host files cannot be cleared and generated ASF License warnings.
