wangrupeng commented on KYLIN-4625: ----------------------------------- Now if you want to debug tomcat without hadoop environment, you can follow the follow steps: * edit the properties of $KYLIN_SOURCE_DIR/examples/test_case_data/sandbox/kylin.properties to local ```log kylin.metadata.url=$KYLIN_SOURCE_DIR/examples/test_case_data/parquet_test kylin.env.zookeeper-is-local=true kylin.env.hdfs-working-dir=file://$KYLIN_SOURCE_DIR/examples/test_case_data/parquet_test kylin.engine.spark-conf.spark.master=local kylin.engine.spark-conf.spark.eventLog.dir=/path/to/local/dir kylin.env=LOCAL ``` * debug org.apache.kylin.rest.DebugTomcat with IDEA && add VM option "-Dspark.local=true" This is used for query engine * start debug tomcat and we can use the models we already defined !screenshot-1.png! > Debug the code of Kylin on Parquet without hadoop environment > ------------------------------------------------------------- > > Key: KYLIN-4625 > URL: https://issues.apache.org/jira/browse/KYLIN-4625 > Project: Kylin > Issue Type: Improvement > Components: Spark Engine > Reporter: wangrupeng > Assignee: wangrupeng > Priority: Major > Attachments: image-2020-07-08-17-41-35-954.png, > image-2020-07-08-17-42-09-603.png, screenshot-1.png > > > Currently, Kylin on Parquet already supports debuging source code with local > csv files, but it's a little bit complex.
