Subject [jira] [Commented] (HADOOP-8202) stopproxy() is not closing the proxies correctly
Date Mon, 26 Mar 2012 03:58:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238088#comment-13238088
] 

Aaron T. Myers commented on HADOOP-8202:
----------------------------------------

Hey Hari, thanks for updating the patch to fix TestHealthMonitor.

bq. There were test failures. However, it does not seem to be related to stopproxy() changes.
I will file jiras on the test failures.

Can you list here which tests failed? Can you comment on Todd's comment that he's surprised
many HDFS tests didn't fail? Perhaps it's because in most tests where we mock out a protocol
object, we never try to close that protocol object. Just a guess.

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.
