fixed the bug : org.apache.gora.util.GoraException:
java.lang.RuntimeException: java.net.MalformedURLException
解决方案：
给hadoop的hadoop-env.sh 添加如下内容
THIRD_LIB=/home/hadoop/soft/lib/hadoopthirdlib
NUTCH_JOB=/usr/local/nutch/runtime/deploy
if [ -d "$THIRD_LIB" ] ; then
export HADOOP_USER_CLASSPATH_FIRST=true
	HADOOP_CLASSPATH=.
	for f in $THIRD_LIB/*.jar; do
		HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f
	done
	for f in $NUTCH_JOB/*.job; do
		HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f
	done
	export HADOOP_CLASSPATH
