Masatake Iwasaki commented on HADOOP-13196:
-------------------------------------------
bq. Changed the default value to 3000 to make sure its backward compatible.
I think this is incompatible change for the code using {{DF(File path,
Configuration conf)}}.
3000 is used if {{DF}} is run as main class (or core-default.xml is not in the
classpath) otherwise 60000 has been the default value since HADOOP-6233.
> DF default interval value is not consistent

>
> In {{core-default.xml}}, the value of the property {{fs.df.interval}} is
> 60000. This value is defined in
> {{CommonConfigurationKeysPublic.FS_DF_INTERVAL_DEFAULT}}, however, this value
> is never used.
> When this property is used in {{DF}}, the default value is
> {{DF.DF_INTERVAL_DEFAULT}} = 3000.
> This can cause potential confusion and should be fixed.
