Subject [jira] Commented: (HADOOP-882) S3FileSystem should retry if there is a communication problem with S3
Date Mon, 22 Jan 2007 21:08:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12466562

James P. White commented on HADOOP-882:
---------------------------------------

I like the idea of a general approach to retries, but using an existing AOP mechanism seems
like a better way to go to me.  Although AspectJ is a strong tool, Spring 2.0 AOP is closer
to what you propose.  In addition to Spring's autoproxies, Spring 2.0 fully supports AspectJ
syntax including annotations.  That provides the greatest flexibility and avoids the invention
of yet-another-syntax for advice.

> File system operations currently fail if there is a communication problem (IOException)
with S3. All operations that communicate with S3 should retry a fixed number of times before
failing.
