错误：

ERROR compiler.Compiler: Javac exception
Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK. It is currently set to "/usr/local/java/jre"

原因：jetty编译jsp类时，ant没有识别到正确的jdk路径。

解决：

ln -s $JAVA_HOME/lib/tools.jar $HIVE_HOME/lib/
