> In one test for hive-477, i found that the below command can not sucessfully
> pass:
> $HADOOP_HOME/bin/hadoop jar
> $HADOOP_HOME/contrib/streaming/hadoop-0.19.0-streaming.jar -input
> /user/hive/warehouse/tablerc1 -output testHiveWriter -inputformat
> org.apache.hadoop.hive.ql.io.RCFileInputFormat -outputformat
> org.apache.hadoop.hive.ql.io.RCFileOutputFormat -mapper
> org.apache.hadoop.mapred.lib.IdentityMapper -jobconf mapred.work.output.dir=.
> -jobconf hive.io.rcfile.column.number.conf=32 -jobconf
> mapred.output.compress=true -numReduceTasks 0
> It is caused by the assumption that RCFileOutputFormat thinks the key's class
> of passes in records is Void.
