Subject [jira] [Commented] (HADOOP-14505) simplify mkdirs() after S3Guard delete tracking change
Date Fri, 16 Jun 2017 15:28:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16052030#comment-16052030

Sean Mackrory commented on HADOOP-14505:
----------------------------------------

So the changes in HADOOP-13760 actually make a batch of mkdirs perform about half as well
as it used to. I've confirmed that this patch fixes it. It won't apply cleanly to trunk right
now just because it includes the new parameter to makeDirsOrders added in HADOOP-14457, so
we could easily reverse the order of those 2 patches if we wanted.

> I noticed after reviewing the S3Guard delete tracking changes for HADOOP-13760, that
mkdirs() can probably be simplified, replacing the use of checkPathForDirectory() with a simple
getFileStatus().
> Creating a separate JIRA so these changes can be reviewed / tested in isolation.
