-----------------------------------
Summary: Remove find-hive-dependency.sh in Kylin 4
Key: KYLIN-5069
URL: https://issues.apache.org/jira/browse/KYLIN-5069
Project: Kylin
Issue Type: Improvement
Reporter: Xiaoxiang Yu
Fix For: v4.1.0
Attachments: image-2021-08-30-16-10-46-712.png
In kylin.sh, Kylin introduces a lot of jars into Kylin instance's class path,
via find-hive-dependency.sh and "hadoop classpath". So class conflict issues
happened often, and most of them are related with hive jars. I think it is
better to remove 'find-hive-dependency.sh' and use SparkSession to fetch Hive
meta.
Following is part of script kylin.sh :
{code:java}
tomcat_classpath=${tomcat_root}/bin/bootstrap.jar:${tomcat_root}/bin/tomcat-juli.jar:${tomcat_root}/lib/*
export
KYLIN_TOMCAT_CLASSPATH=${tomcat_classpath}:${KYLIN_HOME}/conf:${KYLIN_HOME}/lib/*:${KYLIN_HOME}/ext/*:${hadoop_dependencies}:${flink_dependency}
{code}
Some exception looks like this:
