The manual steps I did to verify:
1. compile and run the unit test towards hadoop common module. When I run the
test, there were 9 test failure and 1 test error. But I have verified that
those failure and errors existed in hadoop trunk before I made any changes, and
none of test failure/error was related to this patch
2. Run local debugger in on MiniHadoopClusterManager Class to test if DF load
the correct default interval value(fs.df.interval was removed from
core-default.xml when testing so that DF constructor was forced to read value
from Constant CommonConfigurationKeysPublic.FS_DF_INTERVAL_DEFAULT instead of
from core-default.xml

> According to {{core-default.xml}} the default value of {{fs.df.interval = 60
> sec}}. But the implementation of {{DF}} substitutes 3 sec instead. The
> problem is that {{DF}} uses outdated constant {{DF.DF_INTERVAL_DEFAULT}}
> instead of the correct one
> {{CommonConfigurationKeysPublic.FS_DF_INTERVAL_DEFAULT}}.
