Subject [jira] [Commented] (HDFS-3667) Add retry support to WebHdfsFileSystem
Date Fri, 20 Jul 2012 01:15:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13418857#comment-13418857
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3667:
----------------------------------------------

The patch is actually not big (only 31kB) and a large part of the code is adding getRedirect()
to HttpOpParam.Op and its subclasses.  I think it is unnecessary to decompose it into subtasks.
 Do you have any particular question in your mind?

> DFSClient (i.e. DistributedFileSystem) has a configurable retry policy and it retries
on exceptions such as connection failure, safemode.  WebHdfsFileSystem should have similar
retry support.
