Hi ，I run into some exception while Merge Cuboid Data.I set the auto merge thresholds to 7 days by default, the cube already have 8 segment,so it automatic start a merge job,then fail with exception as follow: =============== Error: java.lang.IllegalArgumentException: Value not exists! at org.apache.kylin.common.util.Dictionary.getIdFromValueBytes(Dictionary.java:162) at org.apache.kylin.common.util.Dictionary.getIdFromValueBytes(Dictionary.java:140) at org.apache.kylin.engine.mr.steps.MergeCuboidMapper.map(MergeCuboidMapper.java:207) at org.apache.kylin.engine.mr.steps.MergeCuboidMapper.map(MergeCuboidMapper.java:63) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:145) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:764) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:340) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:167) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1556) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:162)
seems like it relate to dict,I do have some dimension with dict encoding: [cid:_Foxmail.1@e8154662-2fdc-4074-b4bc-723745b0590b] kylin 1.5.3 some of those segments maybe empty,other not,I think this could be the cause? any idea? ________________________________ 赵天烁 Kevin Zhao [email protected]<mailto:[email protected]> 珠海市魅族科技有限公司 MEIZU Technology Co., Ltd. 广东省珠海市科技创新海岸魅族科技楼 MEIZU Tech Bldg., Technology & Innovation Coast Zhuhai, 519085, Guangdong, China meizu.com
