Atlas UI is not working

[#1]

Hi,

The cluster is not kerberised but installed ranger and atlas. As we are not having plan of search in atlas, we haven't installed solr. Atlas UI is not accessible in our cluster. We could found the following errors in application log:

Please help.

[#2]

looks like atlas is unable to connect to solr . can you check if you can access solr ?

[#3]

we havent installed solr. is it mandatory to install solr if we are not using search?

[#4]

you will need an indexing backend store . Either you can use elastic search /solr . If you are using the HDP2.5 and if you have ambari infra installed on the cluster , you should have solr available.

You will be able to use the same and configure atlas and ranger

atlas.graph.index.search.solr.mode : <zk_host1>:2181/infra-solr,<zk_host2>:2181/infra-solr

if you would like to get a out of box solr installation - try

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_security/content/installing_external_sol...

[#5]

Atlas is still have the same issue after change the above property with with Ambar Infra Solr + Atlas restarted.

if any of the solutions resolved your issue , could you please accept that answer

[#8]

Either Solr or Elastic Search should be installed and started for Atlas to start up. Indexing backend is a hard dependency for Atlas.

[#9]

Can you please share any documents to install solr in HDP-2.5.3 and also the steps to configure it with ranger and atlas.
