I know this question has been asked many times before, but I couldn't find any for this specific case, and this up-to-date. How do I install the Eclipse MapReduce plugin with Hadoop 2.5.2? I've found multiple tutorials addressing this for other versions, and I know that it can be compiled from here, but that link, while it says 2.x, only says up to 2.4.1. I tried to compile it anyway using 2.5.2 using the following command:
ant jar -Dversion=2.4.1 -Dhadoop.version=2.5.2 -Declipse.home=/opt/eclipse -Dhadoop.home=/usr/local/hadoop -DBuildfile: build.xml
This attempted to compile, but then returned
Warning: Could not find file /usr/local/hadoop/share/hadoop/common/lib/jackson-core-asl-1.8.8.jar to copy.
Which makes sense, because the version of this jar in Hadoop 2.5.2 is 1.9.13.
Then I tried to use version 2.5.2, even though it is not mentioned in the jar, since it says that they support 2.x.
ant jar -Dversion=2.5.2 -Dhadoop.version=2.5.2 -Declipse.home=/opt/eclipse -Dhadoop.home=/usr/local/hadoop -DBuildfile: build.xml
In this case, it said BUILD SUCCESSFUL, but there was no output - no jar produced, and no output printed under the 'compile:' and 'jar:' steps.
I even tried downloading the compiled jar from this guy's github, but of course that didn't work either - it didn't show up in Eclipse when I added the jar to the plugins folder.
Is there any way to use the plugin with Hadoop 2.5.2, or do I have to downgrade to 2.4.1? I am using Ubuntu 14.0.4, Hadoop 2.5.2, and Eclipse Luna, but can downgrade that if necessary.
