Caused by: java.lang.NoSuchMethodError: org.apache.hadoop.hbase.client.Scan.setCaching(I)V But I am surprised why setCaching is not there. Could you please check your hbase client jar version(kylin should not package hbase client)? or what is your output for “hbase class path”? It would help if you can share your environment information. Kylin version, hadoop version, hbase version etc.
