Can check if Zookeeper is alive and accepting connections ? I usually check using this command, assuming that the host is localhost and the Zookeeper port is 2181 telnet localhost 2181

can you elaborate more on what kind of dataset you're working with ? Also is Atlas a standalone service or are you using as a part of HDP cluster ?

Can you share some details on how you built/started atlas ? What env are you working on ?

V2 REST documentation can be found here atlas.incubator.apache.org/api/v2/index.html If you find the answer useful, please accept and upvote.

As per my knowledge these are only being used for UI rendering. It acts like additional metadata about the entity.

Like @Ashutosh Mestry said this can be achieved through DSL or Gremlin calls. from DB select count() as 'count' from Table select count() as 'count' Also remember that the count queries are pretty expensive and might take a while to return results as it requires a major graph scan.

https://dev.mysql.com/doc/refman/5.7/en/writing-plugins.html MySQL does offer capability to write plugins which might offer similar functionality as the Hive|AtlasHook.

You can also use the atlas-client artifact (Java) to import the xls metadata into Atlas. I'd recommend going through atlas.incubator.apache.org/api/v2/index.html for an in-depth REST documentation for Atlas (0.8 onwards) Don't forget to upvote/accept the answer if you find it useful.

The latest error that you posted usually means that the data is not being sent correctly to atlas server. Hence when trying to serve the request, atlas fails to process the call. Can you share the application logs from atlas ?

Lineage is generate with type definitions called Process and DataSet, usually when you create these with sufficient information depicting the "Process" of copying "DataSet" from HDFS to Local and similarly for what's happening in the Spark realm, Atlas should be able to generate the Lineage info for you. All you need it to create the Process and Dataset entities for the above scenario. HTH
