[jira] [Created] (HDFS-8071) Redundant checkFileProgress() in PART II of getAdditionalBlock()

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.
