Hi sammer, I have test 3.0.0-alpha2 on HDP3.1 and it works fine for me. After check your output, I guess it is caused by your hbase component. Have you ever check the availability of HBase? Such as create a Hbase table and put some value via hbase shell. And I guess you are using HDP in cloud, I don't know if it has any impact on the availability of Kylin. If you make sure the Hbase is in health state, and still has trouble, please let us know.
