Shengjun Xin commented on HIVE-5132:
------------------------------------

We meet the same issue and copy jasper-compiler-jdt.jar to $HIVE_HOME/lib can resolve this
issue, the error log is:
{code}
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/java/jdk1.7.0_45/jre"
