Hive is part of HDP sandbox. However, you have HDFS and HBase as part of HDF sandbox. To fully use these services, you must allocate more memory to the sandbox’s virtual machine or turn off existing services. If you want these services to automatically start, turn off maintenance mode from within the Ambari dashboard.
