---------------------------------
Summary: MiniDFSCluster should implement AutoCloseable
Key: HDFS-10287
URL: https://issues.apache.org/jira/browse/HDFS-10287
Project: Hadoop HDFS
Issue Type: Improvement
Components: test
Affects Versions: 2.7.0
Reporter: John Zhuge
Assignee: John Zhuge
Priority: Trivial
{{MiniDFSCluster}} should implement {{AutoCloseable}} in order to support
[try-with-resources|https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html].
It will make test code a little cleaner and more reliable.
Since {{AutoCloseable}} is only in Java 1.7 or later, this can not be
backported to Hadoop version prior to 2.7.
