Subject Re: how to build eclipse plugin for hadoop-2.7.1(work on ubuntu15.10)
Date Sun, 06 Dec 2015 11:49:57 GMT
    Thanks for Akira's advice.i have install maven on my PC as Akira says.and successfully
import the hadoop-2.7.1 source into eclipse.so I can browse hadoop source now.
    but it can't resove my problem by doing in this way. I search on the internet,and find
a way to build the hadoop-eclipse-plugin-2.7.1.jar,here is the step:
    1: download the hadoop2x-eclipse-hadoop-master on the github,and extract it into proper
    2:open {$hadoop2x-eclipse-hadoop-master_HOME}/ivy/libraries.properties,and compare the
versions of the various artifacts used by hadoop and components with the jar at the directory
of {$HADOOP_HOME}/share/hadoop/tools/lib.if there is artifact whose version doesn't match,then
change the libraries.properties to match hadoop's jar.
    there is some of changes of mine:
    htrace.version=3.0.4   ==>    htrace.version=3.1.0-incubating
    slf4j-api.version=1.7.5  ==>   slf4j-api.version=1.7.10
    slf4j-log4j12.version=1.7.5  ==> slf4j-log4j12.version=1.7.10
    3:run the shell command:
    >>ant package  -Dversion=2.7.1 -Dhadoop.version=2.7.1 -Declipse.home=/opt/eclipse
    finally i got hadoop-eclipse-plugin-2.7.1.jar  at directory {$hadoop2x-eclipse-hadoop-master_HOME}/build/contrib/eclipse-plugin,and
add it to eclipse.
    unfortunately,when add a new hadoop location,set the host and port.it occurs the error
of this:
    >>An internal error occurred during: "Connecting to DFS hadoop2.7.1".
    >> Could not initialize class org.apache.hadoop.hdfs.DFSConfigKeys.
    here is some of my config:

    I  have tried the port 9002,8032 and 50020 for Map/Reduce(V2) Master, and set the port
9000 for DFS Master.
    does someone knows how to fix it.it has disturbed me for a long time.without fixing this
problem i can't go for next step.i'm extremely looking forward to someone's reply.
