Hi all,
I built a cube on a Hive fact table of about 300 millions rows, all the
steps are FINISHED with success but it seems I cannot do any query.
select * from myFactTable; (or any other query)
returns From line 1, column 15 to line 1, column 43: Table 'MYFACTTABLE'
not found while executing SQL: "select * from myFactTable LIMIT 50000"
I tried rebuilding completely the cube after a purge, created a new
project, etc. but it doesn't solve the issue.
It seems like a new KYLIN_ table has been created and contains data. How
can I know which HBase table corresponds to which cube?
The "Convert Cuboid Data to HFile" step took a while, the MapReduce job
stayed in Undefined status for a long time but finally Succeeded. When I
click on the link from the Kylin UI it send me to 7070/kylin/N/A instead of
the MapReduce job info, is that a bad sign?
In the logs I don't see any error in the Build N-Dimension Cuboid Data,
Calculate HTable Region Splits, Create HTable
I am not sure if it's event related but in the logs can this:

This comes after
Hive Column Cardinality calculation for table
and a step called :

Thanks for your help, I would really like to make this PoC work!
