Hello，I met the same question as yours, but I really dont understand what the links say in your posts, could I get your explaination? just add the value of atlas.rest.address can solve this problem? But I have already add atlas.rest.address = <Atlas-host>:<port> property to atlas-application.properties，By the way, I am using atlas 1.2.0 Here is my atlas-application.properties: atlas.graph.storage.backend=hbase atlas.graph.storage.hbase.table=apache_atlas_janus atlas.graph.storage.hostname=gaoenwei66.cmp3481.interconnect,gaoenwei67.cmp3481.interconnect,gaoenwei65.cmp3481.interconnect atlas.graph.storage.hbase.regions-per-server=1 atlas.graph.storage.lock.wait-time=10000 atlas.EntityAuditRepository.impl=org.apache.atlas.repository.audit.HBaseBasedAuditRepository atlas.graph.index.search.backend=elasticsearch atlas.graph.index.search.index-name=es_janusgraph atlas.graph.index.search.hostname=gaoenwei70.cmp3481.interconnect,gaoenwei68.cmp3481.interconnect,gaoenwei65.cmp3481.interconnect atlas.graph.index.search.elasticsearch.client-only=true atlas.graph.index.search.max-result-set-size=150 atlas.notification.embedded=false #atlas.kafka.data=${sys:atlas.home}/data/kafka atlas.kafka.zookeeper.connect=gaoenwei67.cmp3481.interconnect:2181,gaoenwei66.cmp3481.interconnect:2181,gaoenwei65.cmp3481.interconnect:2181 atlas.kafka.bootstrap.servers=gaoenwei67.cmp3481.interconnect:2181,gaoenwei66.cmp3481.interconnect:2181,gaoenwei65.cmp3481.interconnect:9092 atlas.kafka.zookeeper.session.timeout.ms=400 atlas.kafka.zookeeper.connection.timeout.ms=200 atlas.kafka.zookeeper.sync.time.ms=20 atlas.kafka.auto.commit.interval.ms=1000 atlas.kafka.hook.group.id=atlas atlas.kafka.enable.auto.commit=false atlas.kafka.auto.offset.reset=earliest atlas.kafka.session.timeout.ms=30000 atlas.kafka.offsets.topic.replication.factor=2 atlas.kafka.poll.timeout.ms=1000 atlas.notification.hook.topic.name=ATLAS_HOOK atlas.notification.entities.topic.name=ATLAS_ENTITIES atlas.notification.hook.consumer.topic.names=ATLAS_HOOK atlas.notification.entities.consumer.topic.names=ATLAS_ENTITIES atlas.notification.create.topics=false atlas.notification.replicas=2 atlas.notification.topics=ATLAS_HOOK,ATLAS_ENTITIES atlas.notification.log.failed.messages=true atlas.notification.consumer.retry.interval=500 atlas.notification.hook.retry.interval=1000 atlas.enableTLS=false atlas.authentication.method.kerberos=false atlas.authentication.method.file=true #### ldap.type= LDAP or AD atlas.authentication.method.ldap.type=none #### user credentials file atlas.authentication.method.file.filename=${sys:atlas.home}/conf/users-credentials.properties atlas.rest.address=http://172.21.42.78:21000/ # If enabled and set to true, this will run setup steps when the server starts atlas.server.run.setup.on.start=false atlas.audit.hbase.tablename=apache_atlas_entity_audit atlas.audit.zookeeper.session.timeout.ms=1000 atlas.audit.hbase.zookeeper.quorum=gaoenwei66.cmp3481.interconnect,gaoenwei67.cmp3481.interconnect,gaoenwei65.cmp3481.interconnect:2181 atlas.server.ha.enabled=false atlas.authorizer.impl=simple atlas.authorizer.simple.authz.policy.file=atlas-simple-authz-policy.json atlas.rest-csrf.enabled=true atlas.rest-csrf.browser-useragents-regex=^Mozilla.*,^Opera.*,^Chrome.* atlas.rest-csrf.methods-to-ignore=GET,OPTIONS,HEAD,TRACE atlas.rest-csrf.custom-header=X-XSRF-HEADER atlas.metric.query.cache.ttlInSecs=900 atlas.search.gremlin.enable=false atlas.hook.hive.synchronous=false atlas.hook.hive.numRetries=3 atlas.hook.hive.queueSize=10000 atlas.cluster.name=primary atlas.hook.hbase.synchronous=false atlas.hook.hbase.numRetries=3 atlas.hook.hbase.queueSize=10000 atlas.cluster.name=primary   I really need your help, wish for your answer  ...
