Subject [jira] [Commented] (HADOOP-9489) Eclipse instructions in BUILDING.txt don't work
Date Sun, 01 Mar 2015 18:59:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14342392#comment-14342392

Chris Nauroth commented on HADOOP-9489:
---------------------------------------

Thanks, Tsuyoshi.  If this isn't working consistently, then I'm inclined to abandon the patch.
 Is there anyone else who'd want to pick it up from here and try to work through the errors
Tsuyoshi saw?

> I have tried several times to import Hadoop trunk into Eclipse following the instructions
in the BUILDING.txt file, but so far have not been able to get it to work.
> If I use a fresh install of Eclipse 4.2.2, Eclipse will complain about an undefined M2_REPO
environment variable. I discovered that this is defined automatically by the M2Eclipse plugin,
and think that the BUILDING.txt doc should be updated to explain this.
> After installing M2Eclipse I tried importing the code again, and now get over 2500 errors
related to missing class dependencies. Many of these errors correspond to missing classes
in the oah*.proto namespace, which makes me think that 'mvn eclipse:eclipse' is not triggering
protoc.
