The version of Kylin is 1.5.0, and Hbase’s version is 0.98.
After submit the refresh of cube, I open the monitor page, which looks like this: If I want to drop the cube, Kylin reports this: And the log reports this: 2016-05-14 11:07:58,155 ERROR [http-bio-7070-exec-4] controller.JobController:127 : java.lang.NullPointerException at org.apache.kylin.rest.service.BasicService$1.apply(BasicService.java:138) at org.apache.kylin.rest.service.BasicService$1.apply(BasicService.java:135) at com.google.common.collect.Iterators$8.computeNext(Iterators.java:688) …… Is it a bug of kylin’s web service? -------------------------------- 郑江雨 云平台 Phone: 15155195496
