Hi Yogita,
You can try to remove "jetty-runner" jar from the classpath by excluding it
in "$KYLIN_HOME/bin/find-hive-dependency.sh" and see if the problem still
exists.
find line: hive_lib=`find -L ${hive_lib_dir} -name '*.jar' ! -name '*druid*'
! -name '*slf4j*' ! -name '*avatica*' ! -name '*calcite*' !...
add: ! -name '*jetty-runner*'

Subject: Not able to start Apache Kylin
Hi All,
We are setting up Apache Kylin to be integrated with one of our product.
However, the environment is not going up and running with below error message:

Below are the component successfully setup as a supporting environment for
Kylin:
Hadoop cluster with three nodes.(Hadoop version 2.8.5)
Hbase (Version 1.4.8)
Hive (Version 3.1.1)
Spark 2.4.0
Kylin versions tried:
Kylin 2.6.1
Kylin 2.5.0
Installation Guide followed from here http://kylin.apache.org/docs/install/
We thought of the runtime library difference between tomcat-api.jar and jetty
runner, so tried upgrading both the jars, however, it didn??t produce any
positive results.
Regards,
Yogita Mokate
