Subject [jira] [Created] (HDFS-4308) addBlock() should persist file blocks once
Date Thu, 13 Dec 2012 02:01:21 GMT
Konstantin Shvachko created HDFS-4308:
-----------------------------------------

             Summary: addBlock() should persist file blocks once
                 Key: HDFS-4308
                 URL: https://issues.apache.org/jira/browse/HDFS-4308
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.0.3-alpha
            Reporter: Konstantin Shvachko


FSNamesystem.getAdditionalBlock() persists all file blocks twice, first in {{dir.removeBlock()}}
using OP_ADD, then immediately after that in {{dir.persistBlocks()}} using OP_UPDATE_BLOCKS.
This should be aggregated in one call to logEdit().
