Question

我尝试按照此link的说明创建示例多维数据集。在步骤7中生成失败，并显示以下错误消息。任何帮助表示赞赏

EMR：5.4.0 Hbase：1.3.0 麒麟：2.0.0

java.lang.IllegalArgumentException: Map input splits are 0 bytes, something is wrong! at org.apache.kylin.engine.mr.common.AbstractHadoopJob.getTotalMapInputMB(AbstractHadoopJob.java:573) at org.apache.kylin.engine.mr.steps.CuboidJob.run(CuboidJob.java:134) at org.apache.kylin.engine.mr.MRUtil.runMRJob(MRUtil.java:102) at org.apache.kylin.engine.mr.common.MapReduceExecutable.doWork(MapReduceExecutable.java:123) at org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:124) at org.apache.kylin.job.execution.DefaultChainedExecutable.doWork(DefaultChainedExecutable.java:64) at org.apache.kylin.job.execution.AbstractExecutable.execute(AbstractExecutable.java:124) at org.apache.kylin.job.impl.threadpool.DefaultScheduler$JobRunner.run(DefaultScheduler.java:142) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

结果代码：2

Answer 1

可能日期列为null或记录不在开始日期和结束日期之间。

在logs文件夹中打开kylin.log并检查存储中间数据的查询在hive检查结果中执行该查询是否到来（像这样查询）

""""INSERT OVERWRITE TABLE kylin_intermediate_cube2_70c3e71d_f9a8_4ed1_91a9_d12dd649a9b1 SELECT
