Subject [jira] [Commented] (HADOOP-11009) Add Timestamp Preservation to DistCp
Date Tue, 23 Sep 2014 20:59:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14145423#comment-14145423

Allen Wittenauer commented on HADOOP-11009:
-------------------------------------------

It doesn't look like -p automatically preserves time stamp:
{code}
$ bin/hadoop distcp -p /tmp /a1
...
$ bin/hadoop distcp -pt /tmp /a2
...
$ bin/hadoop fs -ls -R /
drwxr-x---   - aw hdfs          0 2014-09-23 13:52 /a1
-rw-r-----   3 aw hdfs        236 2014-09-23 13:52 /a1/hosts
drwxr-x---   - aw hdfs          0 2014-09-23 13:16 /a2
-rw-r-----   3 aw hdfs        236 2014-09-23 13:16 /a2/hosts
...
drwxr-x---   - aw hdfs          0 2014-09-23 13:16 /tmp
-rw-r-----   3 aw hdfs        236 2014-09-23 13:16 /tmp/hosts
...
{code}

> Currently access and modification times are not preserved on files copied using DistCp.
This patch adds an option to DistCp for timestamp preservation. 
> The patch ready, but I understand there is a Contributor form I need to sign before I
can upload it. Can someone point me in the right direction for this form? Thanks!
