If the job is submitted to yarn. The normal file appender cannot be used. We need to extend a new appender by ourselves to let the log of spark job(both driver and executor) write into HDFS which can be realized in the future. Kylin submit a spark job by a command executor client. It will gather the output of spark job and save into kylin.log . ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
