I have deployed Kylin 0.6.4 to on my HDP 2.1 cluster environment (not sandbox) to get all the latest features and especially all the enhancements in the cube build process.
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 ?*
