Therefore, it's OK to get it via {{CuboidSch= eduler.getBuildLevel()}}. However, for the first building of layered cubing= , we don't know the statistics when create the {{CubingJob}}. Therefore, it= 's better for us to invoke {{CuboidUtil.getLongestDepth(...)}} to estimate = a minimum {{totalLevels}} to reduce the layers for layered cubing. After ca= lculating statistics, thee total depth may also change for {{TreeCuboidSche= duler}}. Then in {{CuboidJob}}, there's a check for whether to skip. > Cubing level calculation inconsistent? > -------------------------------------- > > Key: KYLIN-3342 > URL: https://issues.apache.org/jira/browse/KYLIN-3342 > Project: Kylin > Issue Type: Bug > Reporter: liyang > Priority: Major > Attachments: KYLIN-3342.patch > > > Got below exception during cube build. > {{ Caused by: java.lang.IndexOutOfBoundsException: Index: 7, Size: 7}} > {{ at java.util.ArrayList.rangeCheck(ArrayList.java:635)}} > {{ at java.util.ArrayList.get(ArrayList.java:411)}} > {{ at org.apache.kylin.engine.mr.common.CubeStatsReader.estimateLayerSize= (SourceFile:280)}} > {{ at org.apache.kylin.engine.spark.SparkCubingByLayer.estimateRDDPartiti= onNum(SourceFile:219)}} > {{ at org.apache.kylin.engine.spark.SparkCubingByLayer.execute(SourceFile= :199)}} > {{ at org.apache.kylin.common.util.AbstractApplication.execute(SourceFile= :37)}} > {{ ... 6 more}} > =C2=A0 > Found two way of calculating the level of cuboids > * via CuboidScheduler.getBuildLevel() > * via CuboidUtil.getLongestDepth(...) > We should settle down on one approach. > =C2=A0 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
