I'm not sure if anyone is still > running installations of Hadoop 0.20 but it doesn't seem reasonable to > continue to support them if it adds a maintenance burden. > Removing support for, at minimum, Hadoop versions before 1.0 would start to > reduce the amount of munging that is needed and likely make it easier to > maintain and contribute to the project. > Removing support for Hadoop 1.X versions and support for legacy MapReduce 1 > might remove even more complexity. > If there is concern about users of ancient Hadoop releases who are currently > building from trunk and don't have the option of a production release, we > could do this following a 1.3.0 release which could be declared as the last > release to support Hadoop releases prior to 2.0. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
