[ http://issues.apache.org/jira/browse/HADOOP-652?page=comments#action_12446738 ] Raghu Angadi commented on HADOOP-652: -------------------------------------
This will touch addBlock() in FSDataset.java. As part of this I would like the fix the following as well: a) currently subdirectories are created only in the last sub directory (e.g. subdir63). b) remove siblings array I think it only increase s recursion in addBlock(). > 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 > Reporter: Raghu Angadi > > 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.
