Subject Too high cardinality is not suitable for dictionary
Date Wed, 18 Mar 2015 11:11:58 GMT
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?
