Keval Bhatt reopened ATLAS-1781:
--------------------------------

[~Xinzhi,Luo] I tested your patch it works good for 2 nodes. if we have more then 2 nodes it want render correctly. (i.e arrow color are not in correct order)

To reproduce.

* Run quick start.
* Search for "Table".
* Then go to "sales_fact" entity and check for Lineage.

Please find attached screenshot.
* wrong o/p -> after_test-wrong_op.png
* expected - > expected.png

> I was working with the lineage for hbase, when I added a column family in a hbase table, I want to create a lineage for the table to show there is a change within the table schema, yet when I create a process using the atlas api, I found that the process entity is successfully created, but the lineage is not shown on the atlas web page.
> Steps to Reproduce this issue is: 
> 1. build up an entity extends the DataSet Type
> 2. build up a lineage Process
> 3. set the process input and output to the same entity
> The code is like:
> Referenceable table1 = atlasClient.getEntity(HBaseDataTypes.HBASE_TABLE_TYPE_NAME, AtlasClient.REFERENCEABLE_ATTRIBUTE_NAME, input_table_name);
> Referenceable table2 = atlasClient.getEntity(HBaseDataTypes.HBASE_TABLE_TYPE_NAME, AtlasClient.REFERENCEABLE_ATTRIBUTE_NAME, output_table_name);
> HBaseProcess process = new HBaseProcess("process");
> process.setInput(table1.getId());
> process.setoutput(table2.getId());
> here I set the input_table_name and output_table_name the same string name, when I set them different values, the lineage pic can be shown for table1 and table2 successfully
> Screenshots are:
> 1) The lineage pic keep loading on the atlas UI 
> 2) The error log reported by the browser console
> 3) The lineage pic showed successfully when set the inputs and outputs of the lineage to different entities.
