jay vyas updated MAPREDUCE-5165:
--------------------------------
Description:
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
