Subject Re: Giraph (1.1.0-SNAPSHOT and 1.0.0-RC3) unit tests fail
Date Mon, 30 Jun 2014 08:51:23 GMT
Hi Roman.

I checked out release-1.1.0-RC0 and succeeded to build it.

    $ git checkout release-1.1.0-RC0
    $ mvn clean
    $ mvn package -Phadoop_2 -DskipTests
    ## SUCCESS

However, when I ran the tests with LocalJobRunner, it failed.

    $ mvn clean
    $ mvn package -Phadoop_2

It passed tests from "Core" and "Examples", but it failed at
"Accumulo I/O".


The error log contained the following exception

    java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext,
but class was expected

Next I wanted to run the tests with a running Hadoop2 instance, but
I'm having trouble to set it up (I'm quite new to Hadoop).

Could you show me some example configuration (etc/hadoop/* files) of
Hadoop 2.2.0 single-node cluster? That would be very helpful.
