Metadata Server Web UI in Atlas responds with 503 Service Unavailable

Contributor

Atlas is running but there is a warning sign (yellow) that says HTTP 503 response from Metadata Server Web UI. When I check the /var/log/atlas/application.log, I get:

How do I resolve this? I am using Ambari v2.4.0.1 and HDP v2.4.2.

@J. D. Bacolod

Below is the recommendation from the docs

If you are using Atlas on HDP-2.3 or 2.4; Do Not upgrade to Ambari-2.4.x until you are ready to upgrade to HDP-2.5 with the new version of Atlas.

https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-upgrade/content/upgrading_HDP_pre...

The issue with respect to incompatible versions. So, please plan to upgrade accordingly as per the instructions from above link. Hope this helps.

it looks like the backend is pointing to BerklyDB. would be possible to share the entries in atlas-application.properties for the backend used?

Here's what I have for /etc/atlas/conf/application.properties

atlas.enableTLS=false
atlas.graph.index.search.backend=elasticsearch
atlas.graph.index.search.directory=/var/lib/atlas/data/es
atlas.graph.index.search.elasticsearch.client-only=false
atlas.graph.index.search.elasticsearch.local-mode=true
atlas.graph.storage.backend=berkeleyje
atlas.graph.storage.directory=/var/lib/atlas/data/berkeley
atlas.lineage.hive.process.inputs.name=inputs
atlas.lineage.hive.process.outputs.name=outputs
atlas.lineage.hive.process.type.name=Process
atlas.lineage.hive.table.schema.query.hive_table=hive_table where name='%s'\, columns
atlas.lineage.hive.table.schema.query.Table=Table where name='%s'\, columns
atlas.lineage.hive.table.type.name=DataSet
atlas.notification.embedded=false
atlas.rest.address=http://<host>:21000
atlas.server.address.id1=<host>:21000
atlas.server.bind.address=<host>
atlas.server.ha.enabled=false
atlas.server.http.port=21000
atlas.server.https.port=21443
atlas.server.ids=id1

Unfortunately, I can't see a /var/lib/atlas existing. Should that path be created automatically by Ambari / HDP installation wizard?

@J. D. Bacolod This error might possibly be originating from the missing data folder. Can you try creating the folder manually and restart the server ? If it still doesn't help, can you capture the TRACE or DEBUG logs ?
