             Summary: Kylin Hive Column Cardinality Job unable to read bucketed table
                 Key: KYLIN-1403
                 URL: https://issues.apache.org/jira/browse/KYLIN-1403
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v1.2, v1.3
         Environment: - Tested against apache-kylin-1.2-HBase1.1-incubating-SNAPSHOT-bin and apache-kylin-1.3-HBase-1.1-SNAPSHOT-bin
- Environment is HDP 2.3.4 
- Hive version: hive-1.2.1.2.3.4.0
- HBase version: HBase 1.1.2.2.3.4.0-3485
            Reporter: Sebastian Zimmermann


This issue is connected with https://issues.apache.org/jira/browse/KYLIN-1402 and states the findings while investigating on the StringIndexOutOfBoundsException.

While trying to find out why the outputfile created in the cardinality job is empty, we discovered that the only difference between this non-working job and all our other jobs (which work without problems), is that the underlying table is bucketed. 

The data folder is dbfolder/db/table/partition/bucketfolder/file
Kylin checks for data in dbfolder/db/table/partition and so is unable to find the data.
