Subject [jira] Created: (HDFS-511) Redundant block searches in BlockManager.
Date Tue, 28 Jul 2009 23:31:15 GMT
Redundant block searches in BlockManager.

                 Key: HDFS-511
                 URL: https://issues.apache.org/jira/browse/HDFS-511
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.21.0
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
             Fix For: 0.21.0

Some searches for a block in {{blocksMap}} are redundant and should be eliminated.
{{BlockManager.addStoredBlock()}} contain unnecessary explicit and hidden (inside {{markBlockAsCorrupt()}})
calls of {{blocksMap.getStoredBlock()}}.
