Subject [jira] [Created] (HDFS-2655) BlockReaderLocal#skip performs unnecessary IO
Date Sat, 10 Dec 2011 04:00:40 GMT
BlockReaderLocal#skip performs unnecessary IO
---------------------------------------------

                 Key: HDFS-2655
                 URL: https://issues.apache.org/jira/browse/HDFS-2655
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 0.23.1
            Reporter: Eli Collins


Per HDFS-2654 BlockReaderLocal#skip performs the skip by reading the data so we stay in sync
with checksums. This could be implemented more efficiently in the future to skip to the beginning
of the appropriate checksum chunk and then only read to the middle of that chunk.
