Subject [jira] [Commented] (HADOOP-8202) stopproxy() is not closing the proxies correctly
Date Fri, 23 Mar 2012 23:15:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13237271#comment-13237271
] 

Hari Mankude commented on HADOOP-8202:
--------------------------------------

Including a patch that takes care of concerns

1. Throws HadoopIllegalArgumentexception if proxy is not closeable
2. Throws HadoopIllegalArgumentexception if invocation handler is not closeable
3. New test to catch the error scenario when a null proxy is used.
4. Modified existing negative test so that it does not fail since exception is thrown.
5. Fixed javadoc comments

> I was running testbackupnode and noticed that NNprotocol proxy was not being closed.
Talked with Suresh and he observed that most of the protocols do not implement ProtocolTranslator
and hence the logic in stopproxy() does not work. Instead, since all of them are closeable,
Suresh suggested that closeable property should be used at close.
