Hi Team,
I have installed and setup Kylin on my HDP 2.6 cluster as per the Kylin
documentation. I am able to build the cubes using Map-Red but, not with Spark.
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.
