Atlas is a governance tool. Two of the key pillars of data governance are accountability and meeting compliance requirements. To establish accountability and traceability, tools usually support lineage information. This helps answering questions like where did the data come from, who modified it and how was it modified etc. Compliance requirements for industries like healthcare and the finance industry can be very strict. Origins of the data are required to be known with any ambiguity. Since Atlas claims to help organizations meet their compliance requirements, consider the scenario presented in the attached figure. lineage-accountability.png In the figure we notice a process reads a few data items and then writes them to two different Databases. Atlas can capture cross component lineage and will capture the inputs and the outputs of the process. How can we determine what input went to what database? There can be a situation where all records from data item 1 are written to database two and the remaining two data items are written to database 1. In such a case, I have ambiguity in the lineage. All I would know is that the data could be from any of the data sources. Will such information be enough to meet compliance requirements? The second question I have is regarding performance. Currently Kafka does not support Atlas V2. Therefore when developing the Spark Atlas addon, I used the RESP API to post the entities. Since I am also handling Spark Streaming, in such a case the number of entity notifications can be high. Can I run into scalability issues in such a scenario? Approximately what rate can the REST API handle before messages are dropped? Thanks in advance ... View more

What determines how much lineage will be displayed? I have huge lineage diagrams but it seems atlas randomly chooses to show parts of the tree at different points. Should it not show the entire linage tree if i am at the root data set ? Also Atlas seems to get stuck when I have a linage diagram that consists of 200+ entities. I see the loading wheel forever. thanks ... View more

Hi, I have this scenario where after reading json files I'm doing InvokeHttp against a url attribute in each json file. This returns a further list of json objects with url attribute which I later split and do InvokeHttp individually against each url for result. Now the problem is at the end I need to have a composed json against each flow resulting from the inital json that I read from file along with the later json objects and the final result received after hitting individual url. I need to save this composed json as record in mongodb. I 'm having troubling making this json, so need help regarding the flow and processors. Thanks ... View more

Hi I have the following type defined in atlas. Notice that it extends both Dataset and Process. You can use this URL to post this entity using Postman: http://localhost:21000/api/atlas/v2/types/typedefs { "stuctDefs":[], "classificationDefs": [], "entityDefs" : [ { "name": "spark_testStage", "superTypes" : ["Process", "DataSet"], "attributeDefs" : [ { "name" : "test", "typeName": "string", "isOptional" : true, "cardinality": "SINGLE", "isIndexable": false, "isUnique": false }, { "name": "description", "typeName": "string", "cardinality": "SINGLE", "isIndexable": true, "isOptional": true, "isUnique": false } ] }] } Now i create the following entities using this URL http://localhost:21000/api/atlas/v2/entity { "referredEntities": { "-208942807557405": { "typeName": "spark_testStage", "attributes": { "owner": "spark", "qualifiedName": "Stage6@clusterName", "name": "Stage6", "description": "this is attribute is inclued due to inheritance" }, "guid": "-208942807557405", "version": 0, "inputs": [ { "typeName": "spark_testStage", "attributes": { "source": "testing", "description": null, "qualifiedName": "Stage5@clusterName", "name": "Stage5", "owner": null, "destination": "hdfs://vimal-fenton-4-1.openstacklocal:80ion" }, "guid": "-208942807557404" } ], "classifications": [] } }, "entity": { "guid": "-208942807557404", "status": "ACTIVE", "version": 0, "typeName": "spark_testStage", "attributes" : { "qualifiedName" : "Stage5@clusterName", "name" : "Stage5", "test" : "this is source", "description" : "source", "outputs": [ { "typeName": "spark_testStage", "attributes": { "source": "testing", "description": null, "qualifiedName": "Stage6@clusterName", "name": "Stage6", "owner": null, "destination": "hdfs://vimal-fenton-4-1.openstacklocal:8020/apps/hive/warehouse/destination" }, "guid": "-208942807557405" } ] }, "classifications": [] } } Why doesnt atlas define a line between the two entities. The request is successful but i dont see any lineage. Also I see that stage5 has stage 6 in its output and is correctly linked. I can click on this link on to stage 6 but stage 6 does not have stage 5 as its input. ... View more

Going through the Atlas Technical user guide I see the attribute isComposite, which I do not see in any of the new model definitions for V2. Is this attribute still valid? how can this be specified in v2? I also see that constraints are defined in the Hive mode such as : ownedRef, mappedFromRef,foriegnKey, OnDelete. Where can I get the complete list of constraints and their meaning. What is the relationship for? I see that Hive table refers to array of columns as its attributes and vice versa. and then there is a relationship also defined called hive_table_columns. what additional benefit does creating the relation provide? How to create entities when handling compositions? If the table is composed of columns, will i define columns within the table creation request? An example creation of hive table and column (entities for V2) would be of great help. Thanks @Ashutosh Mestry ... View more

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.

Hi I tried to install apache atlas on my laptop unfortunately I keep on getting exceptions. Can any one make a tutorial to get atlas running on your laptop with embeded Solr and Hbase setting using the link: Apache Atlas Installation How to configure it and what needs to be installed before hand (zookeeper). I just need a basic installation with defaults. It would be great to mention Checkout URL maven commands additional dependencies (softwares) configurations file locations and settings Once you download the repo there are multiple similar folders with the same content which I am confused about, regarding which one to use and where to run the scripts like start_atlas.py etc Thanks ...

How can I configure "shell in a box" to look for the correct hostname. Thanks ... View more
