Hi Experts, In Hadoop 2.x code, there are lots of deprecated properties and many of them have new version in 2.x code.
For example, org.apache.hadoop.mapred.JobConf#MAPRED_JOB_MAP_MEMORY_MB_PROPERTY is deprecated, and its new version is MAPREDUCE_JOB_MAP_MEMORY_MB_PROPERTY. Does MRv2 support the deprecated properties? If yes, which part of source code does this transition work? Thanks in advance!
