Andrzej Bialecki commented on HADOOP-101: ------------------------------------------ Oops, forgot to comment on another point you make: yes, it would be great if we could add an API call to request a datanode to check the status of a given block without sending it to the client, e..g read it physically off the disk and report success/failure. We can do this now only by actually retrieving the block, which is too costly. This is the first version of the tool, any contributions are of course welcome. > DFSck - fsck-like utility for checking DFS volumes > -------------------------------------------------- > > Key: HADOOP-101 > URL: http://issues.apache.org/jira/browse/HADOOP-101 > Project: Hadoop > Type: New Feature > Components: dfs > Versions: 0.2 > Reporter: Andrzej Bialecki > Assignee: Andrzej Bialecki > Attachments: DFSck.java > > This is a utility to check health status of a DFS volume, and collect some > additional statistics. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
