Update ClusterMapReduceTestCase to use MiniDFSCluster.Builder
-------------------------------------------------------------
Key: MAPREDUCE-2623
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2623
Project: Hadoop Map/Reduce
Issue Type: Task
Components: test
Affects Versions: 0.23.0
Reporter: Jim Plush
Priority: Minor
Looking at test class ClusterMapReduceTestCase it issues a warning that the
dfsCluster = new MiniDFSCluster(conf, 2, reformatDFS, null); line of code is
deprecated and MiniDFSCluster.Builder should be used instead. It notes that the
current API will be phased out in version 24. I propose to update the test
class to the most up to date code as it's referenced several places on the
internet as an example of how to write a Hadoop Unit Test.
