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.
> Use single editlog record for creating file + overwrite.

> As discussed in HDFS-6871, as [~jingzhao] and [~cmccabe]'s suggestion, we

> creating file.
