Subject Re: Get Hadoop 0.24.0-SNAPSHOT ready for Eclipse fails on retrieve hadoop-yarn-common jar
Date Fri, 02 Sep 2011 14:11:55 GMT
I believe that if you take off the -e then it will work.  If not run mvn eclipse:clean and
then mvn eclipse:eclipse.  It worked for me yesterday.

Hi all,
I'm trying to download and prepare Hadoop trunk to be used on Eclipse
using https://wiki.apache.org/hadoop/EclipseEnvironment but I'm having
problems with Yarn. In particular the command

mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true -e

output this (this is just the end, other goals compile):
