Subject [jira] [Commented] (HDFS-4979) Implement retry cache on the namenode
Date Tue, 16 Jul 2013 20:16:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13710170#comment-13710170
] 

Konstantin Shvachko commented on HDFS-4979:
-------------------------------------------

Cross posting from HDFS-4942 as this is related to the patch attached here.

> For stateful restarts of RM, this will be used to build retry cache for non-idempotent
request.

Would it make sense then to generalize RetryCache to a common file rather than an inner class
of FSNamesystem?
