Subject [jira] [Created] (HDFS-4152) Add a new class for the parameter in INode.collectSubtreeBlocksAndClear(..)
Date Tue, 06 Nov 2012 04:46:14 GMT
Tsz Wo (Nicholas), SZE created HDFS-4152:
--------------------------------------------

             Summary: Add a new class for the parameter in INode.collectSubtreeBlocksAndClear(..)
                 Key: HDFS-4152
                 URL: https://issues.apache.org/jira/browse/HDFS-4152
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Jing Zhao
            Priority: Minor


INode.collectSubtreeBlocksAndClear(..) currently uses a list to collect blocks for deletion.
 It cannot be extended to support other operation like updating the block-map.  We propose
to add a new class to encapsulate the abstraction.
