Subject RE: A question about `mvn eclipse:eclipse`

Hi Zhoujie,

 

hadoop-yarn-common is failing to resolve hadoop-yarn-api jar file. 

 

Can you try executing install(mvn install -X) on hadoop-yarn-api and then
continue with "mvn eclipse:eclipse -DdownloadSources=true
-DdownloadJavadocs=true -e".

Subject: A question about `mvn eclipse:eclipse`

  

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):
