Subject [jira] [Commented] (HADOOP-15262) AliyunOSS: rename() to move files in a directory in parallel
Date Fri, 16 Mar 2018 02:42:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16401400#comment-16401400

SammiChen commented on HADOOP-15262:
------------------------------------

Hi [~wujinhu], the 006 patch looks overall good. 

One minor issue is the indent in testRenameDirectoryCopyTaskPartialFailed is still "8". It
should be "4". 

Please also upload a patch for branch-2 besides the current patch from trunk. 

And fire a new Jira to update the document for this improvement.

> Currently, rename() operation renames files in series. This will be slow if a directory
contains many files. So we can improve this by rename files in parallel.
