Subject [jira] [Commented] (HDFS-8421) Move startFile() and related operations into FSDirWriteFileOp
Date Thu, 21 May 2015 00:28:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14553416#comment-14553416

Jing Zhao commented on HDFS-8421:
---------------------------------

# We do not need to remove the following check from the beginning of the startFile call.
{code}
checkOperation(OperationCategory.WRITE);
{code}
# The safemode check should only be in the real file creation section
# The following log seems unnecessary to me: in case of Standby NN this change will cause
a lot of warning msg in the log
{code}
+    } catch (IOException e) {
+      NameNode.stateChangeLog.warn("DIR* NameSystem.startFile: " + src + " " +
+          e.getMessage());
{code}
