Atlas Taxonomy subterms are not displayed

[#1]

I created a subterm in Atals Web UI by selecting "Create Subterm" option under Catalogs. The message clearly displays subterm created. I can even retieve all the subterms using the api

http://host:port/api/atlas/v1/taxonomies/Catalog/terms

But they dont appear under Catalog dropdown menu.

On debugging I found Atlas to be calling an API

http://host:port/api/atlas/v1/taxonomies/Catalog/terms?hierarchy/path:.&_=1487799123750

which returns empty json

I changed this API to

http://host:port/api/atlas/v1/taxonomies/Catalog/terms?hierarchy/path:/

and this worked in my java application.

So I changed the URL building javascript TreeLayoutTerm.js to replace hierarchy/path:. -> hierarchy/path:/

Now the request that goes through web ui is something like

http://host:port/api/atlas/v1/taxonomies/Catalog/terms?hierarchy/path:/&_=1487799123750

But still it is fetching empty JSON.

Is this a bug of wrong path being sent to server or is there something I am missing like restart of depending services etc.

Any help would be highly appreciable

treelayoutviewjs.txt@Poorvi Sachar,

Can you make this small change in fetchCollection: function(url, isParent) in Atlas server

webapp/atlas/js/views/business_catalog/TreeLayoutView.js at line 265 and try.

+                    this.childCollection.fetch({ reset: true,cache:true  });

@Nixon Rodrigues

Could you please explain it a bit as when I checked the TreeLayoutView.js file in hdp2.5 sandbox, the line(which you suggested me to change) in fetchCollection: function(url, isParent) is:

this.childCollection.fetch({ reset:true }); similar to what I have in my cluster but in case of hdp2.5 sandbox taxonomy terms are displayed without making the change but for the cluster the terms were not being shown earlier on UI but after the change suggested by you it worked.

@Poorvi Sachar, can you provide version of you both the hdp (meaning working without fix and with fix) ?

@Poorvi Sachar

In HDP 2.5.0.0-1245, atlas version: 0.7.0.2.5 there were some IE issue which got fixed. to avoid caching issue &_=1487799123750 timestamp was appended to api url, but this introduced a regression in taxonomy.

And this bug is fixed in subsequent maint HDP releases, i provided you same fix for 2.5.3.0-37, atlas version: 0.7.0

Hope this clear the doubt.
