Subject [jira] [Commented] (HDFS-6886) Use single editlog record for creating file + overwrite.
Date Fri, 22 Aug 2014 08:24:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14106627#comment-14106627

Yi Liu commented on HDFS-6886:
------------------------------

Right, agree with that if the file exists, then {{checkAncestorAccess}} is to check the parent.

I will update it in next patch version together with update for other guys'  comments.

> As discussed in HDFS-6871, as [~jingzhao] and [~cmccabe]'s suggestion, we could do further
improvement to use one editlog record for creating file + overwrite in this JIRA. We could
record the overwrite flag in editlog for creating file.
