Re: How to submit the patch MAPREDUCE-4490.patch which works for branch-1.2, not trunk?
Hi Arpit, Thanks for your guide! As a new contributor, I still have following two questions need your help: 1) So I guess I should run 'test-patch.sh' on my local environment against branch-1.2, not on Apache Hadoop test server, right? 2) On branch-1.2, I found the 'test-patch.sh' is on ./src/test/bin/test-patch.sh, not ./dev-support/test-patch.sh. My command is 'sh ./src/test/bin/test-patch.sh MAPREDUCE-4490.patch', however failed with message 'ERROR: usage ./src/test/bin/test-patch.sh HUDSON [args] | DEVELOPER [args]'. What's the correct way to manually run 'test-patch.sh'? 2014-02-15 5:25 GMT+08:00 Arpit Agarwal aagar...@hortonworks.com: Hi Sam, Hadoop Jenkins does not accept patches for 1.x. You can manually run 'test-patch.sh' to verify there are no regressions introduced by your patch and copy-paste the results into a Jira comment. On Thu, Feb 13, 2014 at 10:50 PM, sam liu samliuhad...@gmail.com wrote: Hi Experts, I have been working on the JIRA https://issues.apache.org/jira/browse/MAPREDUCE-4490 and attached MAPREDUCE-4490.patch which could fix this jira. I would like to contribute my patch to community, but encountered some issues. MAPREDUCE-4490 is an issue on Hadoop-1.x versions, and my patch based on the latest code of origin/branch-1.2. However, current trunk bases on Yarn and does not has such issue any more. So my patch could not be applied on current trunk code, and it's actually no need to generate a similar patch on trunk at all. How to submit the patch MAPREDUCE-4490.patch only to origin/branch-1.2, not trunk? Is it allowed by Apache Hadoop? Thanks!

This is a problem other than log aggregation. After an MapReduce job completes, the tracking URL is pointing to the MapReduce history server. It is very likely that the history server hasn't been running on your machine, such that you didn't get response from it. - Zhijie On Sun, Feb 16, 2014 at 10:03 PM, EdwardKing zhan...@neusoft.com wrote: Thanks for you help.
