Subject [jira] [Created] (HADOOP-7717) Move handling of concurrent client fail-overs to RetryInvocationHandler
Date Mon, 03 Oct 2011 21:00:34 GMT
Move handling of concurrent client fail-overs to RetryInvocationHandler
-----------------------------------------------------------------------

                 Key: HADOOP-7717
                 URL: https://issues.apache.org/jira/browse/HADOOP-7717
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 0.24.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers
             Fix For: 0.24.0


Currently every implementation of a {{FailoverProxyProvider}} will need to perform its own
synchronization to ensure that multiple concurrent failed calls to a single client proxy object
don't result in multiple client fail over events. It would be better to put this logic in
{{RetryInvocationHandler.invoke}}.

This is based on feedback provided by Todd in [this comment|https://issues.apache.org/jira/browse/HDFS-1973?focusedCommentId=13119567&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13119567].
