This takes care of nearly all the review comments so far, save the following: 1. Preserve-status on the root-directory: I've left it out, because this can't really be handled. (For instance, if there are more than one source-path, it is ambiguous to determine the target-root's permissions.) 2. The count in deleteMissing(): It turns out that this is accurate. I've also modified -atomic not to blow away the target-path, if it exists. This will need removing before an atomic commit can be made. As per Amareshwari's advice, this is checked before the copy is initiated. (There's also a check just before the commit is done, as a corner case. The copied data is retained in the temporary workspace.) Tests have been altered accordingly. (We briefly toyed with the idea of using -overwrite along with -atomic, to forcibly overwrite the target, but this mixes disjoint concerns, while only offering the dubious convenience of deleting pre-existing targets. We're leaving -atomic and -overwrite mutually exclusive.) I'm leaving it mavenized, so that it may be built from mapreduce/src/contrib/distcpv2/ by "mvn package". The jar may then be used with "bin/hadoop jar hadoop-distcp.jar [OPTIONS]". The usage is described at greater length in the pdf generated in the build.

[jira] [Commented] (MAPREDUCE-2764) Fix renewal of dfs delegation tokens

It removes all of the current guess work that is currently done. hdfs tokens -> always use nn:rpc-port, only used for rpc hftp tokens -> always use nn:http-port, only used for hftp by having a renewer for each kind of token, they are simpler. The only hiccup is needing to have the hftp client translate the token to hdfs to provide wire compatibility. Of course the long term solution has to be to move to a serialization library that allows us to add/remove fields. Writable doesn't. :( > Fix renewal of dfs delegation tokens > > > Key: MAPREDUCE-2764 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2764 > Project: Hadoop Map/Reduce > Issue Type: Bug >Reporter: Daryn Sharp >Assignee: Daryn Sharp > Fix For: 0.20.205.0 > > Attachments: MAPREDUCE-2764.patch > > > The JT may have issues renewing hftp tokens which disrupt long distcp jobs. > The problem is the JT's delegation token renewal code is built on brittle > assumptions.

If that fails due > to a {{VersionMismatchException}}, it tries https based on another assumption > that it must be hftp if it's not hdfs.

[jira] [Updated] (MAPREDUCE-901) Move Framework Counters into a TaskMetric structure
[ https://issues.apache.org/jira/browse/MAPREDUCE-901?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Arun C Murthy updated MAPREDUCE-901: Attachment: MAPREDUCE-901.patch_2 Updated patch to fix a couple of unit tests, which now pass. I think with MAPREDUCE-279, the counter limits are less interesting given that they do not affect other jobs - unlike MRv1 where this would affect the JobTracker. For now, I propose we commit this and re-visit Counter limits via a follow-on (blocker) jira.
