Subject [jira] [Commented] (HADOOP-13488) Have TryOnceThenFail implement ConnectionRetryPolicy
Date Mon, 15 Aug 2016 05:34:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15420631#comment-15420631

Xiaobing Zhou commented on HADOOP-13488:
----------------------------------------

I posted the initial patch v000. The high level idea is introducing ConnectionRetryPolicy
extending RetryPolicy, which clarified semantics of doing connection retry. For easy implementation
of subclasses, AbastractConnectionRetryPolicy is also provided.

> As the most commonly used default or fallback policy, TryOnceThenFail is often used both
RetryInvocationHandler and connection level. As proposed in HADOOP-13436, it should implement
ConnectionRetryPolicy.
