[jira] [Commented] (HDFS-8394) Move getAdditionalBlock() and related functionalities into a separate class

    [ https://issues.apache.org/jira/browse/HDFS-8394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14542764#comment-14542764 ] 

Haohui Mai commented on HDFS-8394:
----------------------------------

The v0 patch focuses on moving the code into a separate class. It tries to minimize the changes.

The most notable change is in {{FSNamesystem#getAdditionalBlock()}}. It moves the core implementation of the two parts of the functions to {{FSDirWriteFileOp}} and keeps the safemode checks within the FSNameSystem.
