Subject [jira] [Commented] (HDFS-2246) Shortcut a local client reads to a Datanodes files directly
Date Fri, 18 Nov 2011 00:56:52 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13152526#comment-13152526
] 

Tsz Wo (Nicholas), SZE commented on HDFS-2246:
----------------------------------------------

> Is it ok if I address the ACL configuration and ugi in cache keys in a separate jira
for trunk and let 20s support only one user?

This makes sense.

One minor comment for the latest patch:
- The name "dfs.client.read.shortcircuit.checksum" is not clear whether it is to enable checksum
or it is to skip checksum.

-----
Todd, would you like review the 0.20 patch?
