It always fails right after I click the build and gives a popup "Oops org/apache/spark/api/java/function/Function". I looked at "kylin.log" too and it says the same in stack trace pasted below. I have a copy of hive-site.xml under KYLIN_HOME/hadoop-conf where the value of "hive.execution.engine" is set to "mr". Please help me understand what other things to check for this error.
