Description

While HADOOP-6234 added dfs.umaskmode in 0.21.0, the subsequent HADOOP-6233 simply renamed it, again in 0.21.0, without any deprecation mechanism (understandable).

However, 1.x now carries dfs.umaskmode but there isn't a graceful deprecation when one upgrades to 2.x. We should recreate this prop and add it to the deprecated list.
