    Affects Versions: 0.20-append
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor
             Fix For: 0.20-append
         Attachments: hdfs-1248.txt

Last remaining bits of my append branch that didn't fit elsewhere in JIRA (just misc cleanup)
 - Slight cleanup to recoverFile() function in TFA4
 - Improve error messages on OP_READ_BLOCK
 - Some comment cleanup in FSNamesystem
 - Remove toInodeUnderConstruction (not used)
 - Add some checks for null blocks to avoid NPE
 - Only log "inconsistent size" warnings at WARN level for non-under-construction blocks.
 - Redundant addStoredBlock calls are also not worthy of WARN level
 - Add some extra information to a warning in ReplicationTargetChooser

This may need HDFS-1057 to be committed first to apply.
