Does MRv2 support the deprecated properties?
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!

Hey sam:
Please take a look at
hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/util/ConfigUtil.java
Thanks
