I rebuilt the source code with the fix for issue 630, then, I select 2 segments to merge, and each segment contains just one day's data, however, the following error occurs,
org.apache.kylin.job.exception.ExecuteException: org.apache.kylin.job.exception.ExecuteException: java.lang.IllegalArgumentException: Too high cardinality is not suitable for dictionary -- DEFAULT.TEST.MYDATE cardinality: 7304854 is there any suggestion about it?
