View logs through kylin WebUI
When enabled SparkExecutorHdfsAppender SparkDriverHdfsAppender, users can download driver logs from kylin's WebUI, even the spark.submit.deployMode is cluster(means the driver is not located at the same node of Kylin Job Server).
By default, the Output will only show the contents of the first and last 100 lines of all logs of this step. if you need to view all logs, you can click "download the log file" at the top of the Output window to download all logs, and then the complete spark driver log file of this step will be downloaded locally by the browser.

vim ${KYLIN_HOME}/conf/spark-driver-log4j.properties
