HBase is the default datastore for atlas. So, as part of atlas startup script, it sets up required hbase tables to store the metadata.
From the logs, it looks like HBase master is in its initialization phase and is not completely running yet.. I would suggest to wait for the hbase master and region server to come up completely. If it is stuck then try restarting hbase service. You can check the status of hbase services through Ambari. Hope this helps.
