Chris Douglas commented on MAPREDUCE-1522:
------------------------------------------
All test failures are due to Hudson's recent abject uselessness:
{noformat}
java.lang.NoClassDefFoundError: org/apache/hadoop/conf/Configuration

The former test results hold, as:
# The original run failed only {{TestMRLocalFS}} due to MAPREDUCE-1520
# The only changes are in the unit test, which passes
> FileInputFormat may change the file system of an input path
