[ http://issues.apache.org/jira/browse/HADOOP-652?page=comments#action_12448799 ] Raghu Angadi commented on HADOOP-652: -------------------------------------
You should update your code. FSDataset.java has changed recently. Also do a 'diff -u' for submitting a patch. This fixes only updating numBlock and does not fix recursion. I am thinking of fixing both (a) and (b) in comment #1 above. > Not all Datastructures are updated when a block is deleted > ---------------------------------------------------------- > > Key: HADOOP-652 > URL: http://issues.apache.org/jira/browse/HADOOP-652 > Project: Hadoop > Issue Type: Bug > Components: dfs > Affects Versions: 0.8.0 > Reporter: Raghu Angadi > Attachments: FSDataset.java.patch > > > Currently when a block is deleted, DataNode just deletes the physical file > and updates its map. We need to update more things. For e.g. numBlocks in > FSDir is not decremented.. effect of this would be that we will create more > subdirectories than necessary. It might not show up badly yet since numBlocks > gets correct value when the dataNode restarts. I have to see what else needs > to be updated. -- 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
