Hemanth Yamijala commented on ATLAS-658:
----------------------------------------
[~kevalbhatt18], [~bergenholtz], UI indeed looks good for lineage. Things were
fine with quick start data. However, there are few issues with hive data when I
tested the integration. Can you please look into these:
* The logic to determine when to show a dataset (table) icon and when to show a
process (gear) icon seems wrong. So, the code is explicitly checking for type
== "Table" which is a problem (in {{LineageLayoutView.js}}), because there are
other data types (hive_table, kafka_topic, etc). Because of the hardcoding,
right now we are showing a gear icon for hive_tables as well. The dashboard v1
code had developed some logic to determine which is a dataset and which is a
process. The same should be replicated here, I think.
* I ran couple of hive queries as follows:
{code}
create table test1(id int, name string, description string);
create table test1_ctas as select name, count(name) from test1 group by name;
create table test1_ctas2 as select id, count(name) from test1 group by id;
{code}
With these, the expected lineage is that test1 should have one set of edges
leading to test1_ctas and another to test1_ctas2. In the lineage that shows up,
only one set of edges are seen, although all vertices are seen. I will upload
the image of the lineage graph so you can relate to this comment with the name
{{atlas_658_hive_lineage_issues.png}}.
