Hi Olivier, as I know from 0.6.2 to 0.6.4 it just contains bug fixes, no metadata structure change;
Your problem matches a case I encountered some times: there is no data records in the selected date range; Please check and ensure that there is at least 1 row in that date range. You can find out the intermediate hive table name from Kylin log, and then check its hdfs file size, or execute “select count (*)” in Hive. If the number is 0, that is just the problem, you need populate some new test data. If not, please attache the Kylin log so we can have a check.

I was running Kylin 0.6.2 previously on this environment and I could create a small cube successfully and access the results through Tableau. I didn't drop the metadata tables in the upgrade process so that I could keep the existing cubes and the metadata of the imported tables. Is this the way to proceed with upgrades ? Or shall I remove manually all metadata when upgrading Kylin ? I can connect without any issue to version 0.6.4 and see all the changes in Kylin web front-end. But I can't create any new cube. The cube building process is stuck in pending status after stage #1 Step Name: Create Intermediate Flat Hive Table. It looks like stage #2 is not being launched. I can't see any Map Reduce job being executed for stage #2 nor any relevant information in Kylin.log. I have attached the corresponding extract of Kylin.log. Any idea on how I should troubleshoot this upgrade issue ?
