Subject [jira] [Created] (HDFS-8071) Redundant checkFileProgress() in PART II of getAdditionalBlock()
Date Mon, 06 Apr 2015 22:15:12 GMT
Konstantin Shvachko created HDFS-8071:
-----------------------------------------

             Summary: Redundant checkFileProgress() in PART II of getAdditionalBlock()
                 Key: HDFS-8071
                 URL: https://issues.apache.org/jira/browse/HDFS-8071
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.3-alpha
            Reporter: Konstantin Shvachko


{{FSN.getAdditionalBlock()}} consists of two parts I and II. Each part calls {{analyzeFileState()}},
which among other things check replication of the penultimate block via {{checkFileProgress()}}.
See details in HDFS-4452.
Checking file progress in Part II is not necessary, because Part I already assured the penultimate
block is complete. It cannot change to incomplete, unless the file is truncated, which is
not allowed for files under construction.
