First thought is that I would check to see if you're somehow pulling in a xerces \
library that your version of Hadoop wasn't built against.  Can you provide your pom \
file?  Also, I would do a mvn dependencies:list and see if something looks off. You \
should probably paste the output of that for others on this list also.

Ok, this drives me into nuts.

I got a junit test case as simple as below:

  @Before
public void setup() throws IOException {
    Job job = Job.getInstance();
    Configuration config = job.getConfiguration();

And I got Exception at Job.getInstance() as:

  java.lang.UnsupportedOperationException:  setXIncludeAware is not supported on this \
JAXP implementation or earlier: class \
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

  at javax.xml.parsers.DocumentBuilderFactory.setXIncludeAware(DocumentBuilderFactory.java:614)

What is strange is that the same code works in windows but not on Linux. Even on \
Linux, only one class is facing the problem. Other classes are fine running the exact \
same code.  On that problematic class, there are four test methods, one is successful \
and three are failing.

Anyone has similar experience?


I have Hadoop 2.7.1, hive 1.2.1 and hbase 1.1.2. and I am running with maven 3.3.3 \
and/or 3.3.9.
