-----------------------------
Resolution: Won't Fix
> PigServer throws exception if it cannot find hadoop-site.xml or core-site.xml

> Hi
> We've been using the Hadoop MiniCluster to do unit testing of our pig scripts
> in the following way.
> MiniCluster minicluster = MiniCluster.buildCluster(2,2);
> pigServer = new PigServer(ExecType.MAPREDUCE, minicluster.getProperties());
> This has been working fine for 0.6 and 0.7.
> However in the trunk (0.8) looks like there is change due to which an
> exception is thrown if hadoop-site.xml or core-site.xml is not found in the
> classpath.
> org.apache.pig.backend.executionengine.ExecException: ERROR 4010: Cannot find
> hadoop configurations in classpath (neither hadoop-site.xml nor core-site.xml
> was found in the classpath).If you plan to use local mode, please put -x
> local option in command line
> at
> org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.init(HExecutionEngine.java:149)

> at org.apache.pig.PigServer.<init>(PigServer.java:204)
> at org.apache.pig.PigServer.<init>(PigServer.java:200)
> The problem seems to be
> org.apache.pig.backend.hadoop.executionengine.HExecutionEngine: 148
> if( hadoop_site == null && core_site == null ) {
> throw new ExecException("Cannot find hadoop configurations in
> classpath (neither hadoop-site.xml nor core-site.xml was found in the
> classpath)." +
> "If you plan to use local mode, please put -x
> local option in command line",
> 4010);
> }
> We would like to use the mapreduce mode but with the minicluster and have a
> lot of unit test with that setup.
> Can this check be removed from this level ?
> Thanks
