jay vyas commented on MAPREDUCE-5165:
-------------------------------------
+1 to close, but the deprecation story is somewhat tricky not sure how to
improve it. Maybe just a wiki page update to
http://wiki.apache.org/hadoop/HowToContribute to explain the changes to
MRMiniCluster would be in order here, or something.
> Create MiniMRCluster version which uses the mapreduce package.

> Key: MAPREDUCE-5165
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5165
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: jay vyas
> Priority: Minor
>
> The MiniMapRedCluster class references some older mapred.* classes (as per
> comments below however, there is the MiniMRYarnCluster, which may aim to
> replace it).
> It could be recreated in the mapreduce package to use the Configuration class
> instead of JobConf, which would make it simpler to use and integrate with new
> FS implementations and test harnesses that use new Configuration (not
> JobConf) objects to drive tests.
> This could be done many ways:
> 1) using inheritance or else
> 2) by copying the code directly
> The appropriate implementation depends on wether or not
> 1) Is it okay for mapreduce.* classes to depend on mapred.* classes ?
> 2) Is the mapred MiniMRCluster implementation going to be deprecated or
> eliminated anytime?
> 3) What is the future of the JobConf class - which has been deprecated and
> then undeprecated ?
> Note that This is all intimately linked to the role that MiniMRYarnCluster
> will play. Relevant classes:
> .//hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/test/java/org/apache/hadoop/mapred/MiniMRClientCluster.java
> .//hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/test/java/org/apache/hadoop/mapred/MiniMRClientClusterFactory.java
