Atlas Rest API V2 Error

Expert Contributor

Hi I have installed atlas naively (not HDP). I tried to use the REST API but I notice that the V2 API does not work. I have the latest build from

 https://git-wip-us.apache.org/repos/asf/atlas.git atlas 

Atlas is running locally. I have used the following configuration

mvn clean package -Pdist,berkeley-elasticsearch

I notice I keep getting the following warning in my application log:

2017-09-12 13:16:34,998 WARN  - [main-SendThread(localhost:9026):] ~ Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect (ClientCnxn$SendThread:1102)
java.net.ConnectException: Connection refused

	at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1081)

When i hit the URL below I get the expected response.

localhost:21000/api/atlas/types

But when I try

localhost:21000/api/atlas/v2/types

I get the following error in the log:

2017-09-12 13:16:35,000 ERROR - [pool-1-thread-7 - 32b40c72-e4ba-41cd-aded-62634756785a:] ~ Error handling a request: e454ceee5c6d9335 (ExceptionMapperUtil:32)

The URL mentioned above is mentioned in

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_data-governance/content/atlas_types_api....

The REST API Page for atlas has the following URL

https://atlas.apache.org/api/v2/types/typedefs

when I try this URL i get the following message 404 message

Looking for something? We're sorry. The web address you're looking for is not a functioning page in Apache Atlas. Please try navigating from Apache Atlas Home

Any suggestions?

I am trying the recently posted GitHub examples from Venkat https://github.com/venkatra/atlas-v2

My system is not empty and I suspect I am getting collisions but I get this message

There was an error processing your request. It has been logged (ID c3168fa1ecad582d)

When is scan the application.log with that ID I get the following message

2018-04-27 15:57:50,312 ERROR - [pool-1-thread-5 - 2f8110b3-0d18-4435-8ccd-3a8abff0eda0:] ~ Error handling a request: c3168fa1ecad582d (ExceptionMapperUtil:32)

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `org.apache.atlas.model.typedef.AtlasTypesDef` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('classificationDefs')

... and a whole bunch of stack trace

What is the correct way to determine root cause ?

I am working with Atlas-1.0.0-alpha if that is important

I found this problem was caused by missing all of the JSON so I had a missing { but still keen to understand the problem solving process.
