John Zhuge resolved YARN-4959. ------------------------------ Resolution: Not A Problem Fix Version/s: 2.7.0 Already supported because: * {{MiniYARNCluster}} inherits from {{CompositeService}} => {{AbstractService}} => {{Service}} => {{Closeable}} => {{AutoCloseable}}. * {{AbstractService.close}} calls {{stop}} which calls {{serviceStop}}. * {{MiniYARNCluster}} performs cleanup in its overridden {{serviceStop}} Thanks, [~boky01], for point it out in a comment for HDFS-10287. > MiniYARNCluster should implement AutoCloseable > ---------------------------------------------- > > Key: YARN-4959 > URL: https://issues.apache.org/jira/browse/YARN-4959 > Project: Hadoop YARN > Issue Type: Improvement > Components: test > Affects Versions: 2.7.0 > Reporter: John Zhuge > Priority: Trivial > Fix For: 2.7.0 > > > {{MiniYARNCluster}} 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
