Hi there,   I added Atlas in my CDP cluster, and find can't connect the web UI.  In the application.log, I found the error: Can not find the specified config set: vertex_index. I followed the instruction in the following links, but still couldn't get it to work. Any suggestions? https://issues.apache.org/jira/browse/AMBARI-18368 https://community.cloudera.com/t5/Support-Questions/Atlas-UI-not-available-Service-Unavailable/td-p/132435   Here is the application.log:                               Atlas Server (STARTUP)   project.name: apache-atlas project.description: Metadata Management and Data Governance Platform over Hadoop build.user: jenkins build.epoch: 1574150696506 project.version: 2.0.0.7.0.3.0-79 build.version: 2.0.0.7.0.3.0-79 vc.revision: cbb309de67ee0215efa0763f03c2f32f40f1d8f3 vc.source.url: scm:git:git://git.apache.org/atlas.git/atlas-webapp ######################################################################################## (Atlas:215) 2020-04-21 16:41:34,562 INFO  - [main:] ~ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> (Atlas:216) 2020-04-21 16:41:34,562 INFO  - [main:] ~ Server starting with TLS ? false on port 31000 (Atlas:217) 2020-04-21 16:41:34,562 INFO  - [main:] ~ <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< (Atlas:218) 2020-04-21 16:41:35,236 INFO  - [main:] ~ No authentication method configured.  Defaulting to simple authentication (LoginProcessor:102) 2020-04-21 16:41:35,315 WARN  - [main:] ~ Unable to load native-hadoop library for your platform... using builtin-java classes where applicable (NativeCodeLoader:60) 2020-04-21 16:41:35,397 INFO  - [main:] ~ Logged in user atlas (auth:SIMPLE) (LoginProcessor:77) 2020-04-21 16:41:36,202 INFO  - [main:] ~ Not running setup per configuration atlas.server.run.setup.on.start.
