我遵循教程为流立方体建设从
kylin cube from streaming（Kafka）
所有的属性都是在上面提到的页面中设置的。
但是当触发来构建立方体的时候。在第一步保存Kafka的数据失败
说：
org.apache.kylin.engine.mr.exception.MapReduceException: no counters for job job_1547096967734_0086

at java.lang.Thread.run(Thread.java:748)我见过ApacheKylinCube在“没有作业计数器”时失败
但是这里的用例是用于普通的立方体构建，而不是通过kafka立方体构建流。
在mapred-root-historyserver.log中，下面的条目似乎没有帮助。

请检查mr作业中Yarn上的第一个立体步骤。在作业中，您可以深入到每个Map器的日志中，然后您应该能够在那里看到一些异常。通常，可能的原因包括“无法与kafka连接”、“无法加载kafka客户端jar”等。

看来你的环境有问题。您可以查看错误消息的更多日志。你最好参考最新的文件http://kylin.apache.org/docs/tutorial/cube_streaming.html. 如果你想尽快启动Kylin。建议您试用kylin或使用集成沙盒（如hdp沙盒）开发它，并确保它至少有10gb内存。

我们可以通过在yarn-share-lib中提供kafka-client-2.0.0.jar来修复它。如mapreduce作业日志所示，未找到kafka的类def。
