Description

When I deploy kylin-2.0 in my env and job execute failed, When send email of job status changed, I get the exception :
java.lang.IllegalArgumentException: Illegal group reference

This is because error message contain special character like '$' or '\', replaceAll will throw exception while encounter this string. http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#replaceAll(java.lang.String, java.lang.String)

What is more, Kylin can not send error message of last executable job, I modify it too...
