Subject [jira] Commented: (HADOOP-3193) Discovery of corrupt block reported in name node log
Date Wed, 14 May 2008 23:27:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596977#action_12596977
] 

Sameer Paranjpye commented on HADOOP-3193:
------------------------------------------

I'd like to do more here. In addition to reporting corrupt blocks in the log, the Namenode
should try and determine *where* the corruption occured i.e. on disk on the Datanode vs elsewhere
(network transmission or in memory on the client).
