Hi guys: A breif check wiht "find ./ -name *ConfigKeys*" doesn't seem to indicate that there is a "MapRedConfigKeys" class... Should there be one to help get rid of magic numbers and unify the namespace? This seems to be the goal of the DFSConfigKeys class in the HDFS source tree.
... Or are there differences in the way configuration values are handled in mapred versus hdfs code bases ? For example : "job.getInt(JobContext.IO_SORT_FACTOR, 100)" in the ReduceTask class would more typically be implemented (if in hdfs) using the DFSConfigKeys static class which stores defaults and configuration parameter names. Just curious wether there is any goal to take the Mapred configuration values and unify their namespace in mapred/common in the same way that seems to have been done in hdfs using the DFSConfigKeys class. -- Jay Vyas http://jayunit100.blogspot.com
