Subject [jira] [Commented] (HDFS-2246) Shortcut a local client reads to a Datanodes files directly
Date Thu, 11 Aug 2011 17:44:30 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13083272#comment-13083272
] 

Sanjay Radia commented on HDFS-2246:
------------------------------------

HDFS-347 discusses ways to optimize reads for local clients. A clean design is fairly involved.
A shortcut has been proposed
where the client access the hdfs file blocks directly; this works if the client is the same
user/group as the DN daemon. 
This is non-invasive and is a good short term solution till HDFS-347 is completed.
