I installed Hadoop version 1.0.3 and its related eclipse plugin successfully. All the Hadoop functionalities and examples are working pretty well, but when I want to use its plugin on eclipse, it could not connect to hdfs and I get the error:
An internal error occurred during: "Connecting to DFS localhost". org/apache/commons/configuration/Configuration.
could anybody help me how to solve this problem! Thanks
You are facing this problem because the plugin is missing some necessary jars. In order to solve the problem you need to rebuild the plugin after including the necessary jars. I have seen this kind of questions a lot on SO, and they all point out to the same thing. Please see these links :
I did follow the following blog instructions to make Hadoop eclipse plugin 1.0.4 : http://iredlof.com/part-4-compile-hadoop-v1-0-4-eclipse-plugin-on-ubuntu-12-10/
but it seems it has some missing parts like:
in MANIFEST.MF you should add:
/lib/commons-cli-1.2.jar
and in build-contrib.xml you should also add:
<property name="commons-cli.version" value="1.2"/>
I hope these are useful!
you must run hadoop with command line first!!
./[hadoop-path]/bin/start-all.sh
