Hi kylin team:
kylin-2.6.3 使用MapReduce已经成功构建smaple cube。 然后clone了一份kylin_sales_cube修改为Spark，build 报错。 Spark是使用脚本下载的，配置参考了http://kylin.apache.org/cn/docs/tutorial/cube_spark.html。 $KYLIN_HOME/bin/download-spark.sh jar cv0f spark-libs.jar -C $KYLIN_HOME/spark/jars/ . hadoop fs -mkdir -p /kylin/spark/ hadoop fs -put spark-libs.jar /kylin/spark/ ... 报错日志： Caused by: java.lang.NoClassDefFoundError: org/apache/spark/api/java/function/Function at org.apache.kylin.engine.spark.SparkBatchCubingJobBuilder2.<init>(SparkBatchCubingJobBuilder2.java:53) ~[kylin-engine-spark-2.6.3.jar:2.6.3] at org.apache.kylin.engine.spark.SparkBatchCubingEngine2.createBatchCubingJob(SparkBatchCubingEngine2.java:44) ~[kylin-engine-spark-2.6.3.jar:2.6.3] at org.apache.kylin.engine.EngineFactory.createBatchCubingJob(EngineFactory.java:60) ~[kylin-core-job-2.6.3.jar:2.6.3] at org.apache.kylin.rest.service.JobService.submitJobInternal(JobService.java:234) ~[kylin-server-base-2.6.3.jar:2.6.3] at org.apache.kylin.rest.service.JobService.submitJob(JobService.java:202) ~[kylin-server-base-2.6.3.jar:2.6.3] at org.apache.kylin.rest.controller.CubeController.buildInternal(CubeController.java:395) ~[kylin-server-base-2.6.3.jar:2.6.3] ... 77 more Caused by: java.lang.ClassNotFoundException: org.apache.spark.api.java.function.Function at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1928) ~[catalina.jar:7.0.91] at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1771) ~[catalina.jar:7.0.91] at org.apache.kylin.engine.spark.SparkBatchCubingJobBuilder2.<init>(SparkBatchCubingJobBuilder2.java:53) ~[kylin-engine-spark-2.6.3.jar:2.6.3] at org.apache.kylin.engine.spark.SparkBatchCubingEngine2.createBatchCubingJob(SparkBatchCubingEngine2.java:44) ~[kylin-engine-spark-2.6.3.jar:2.6.3] at org.apache.kylin.engine.EngineFactory.createBatchCubingJob(EngineFactory.java:60) ~[kylin-core-job-2.6.3.jar:2.6.3] at org.apache.kylin.rest.service.JobService.submitJobInternal(JobService.java:234) ~[kylin-server-base-2.6.3.jar:2.6.3] at org.apache.kylin.rest.service.JobService.submitJob(JobService.java:202) ~[kylin-server-base-2.6.3.jar:2.6.3] at org.apache.kylin.rest.controller.CubeController.buildInternal(CubeController.java:395) ~[kylin-server-base-2.6.3.jar:2.6.3] 报错之后，再去提交build，又报新的错： Caused by: org.apache.kylin.rest.exception.BadRequestException: The cube kylin_sales_cube_clone_spark has segments [kylin_sales_cube_clone_spark[20120101000000_20140201235500]], but none of them is READY.
