Subject [jira] [Updated] (HDFS-4979) Implement retry cache on the namenode
Date Wed, 17 Jul 2013 22:08:48 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4979?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suresh Srinivas updated HDFS-4979:
----------------------------------

    Attachment: HDFS-4979.3.patch

Here is an updated patch.

I had a chat with [~jingzhao], who suggested changes to move retryCache processing out of
FSNamesystem lock.

Briefly, addressing one of the comments from Chris, about refactoring repeated code; this
is not straight forward because of the needs for returning a value from method replaying the
response. Please look at the latest. Unfortuanaely it has changed quite a bit.
