Review request for atlas, Madhan Neethiraj and Suma Shivaprasad.
Bugs: ATLAS-772
https://issues.apache.org/jira/browse/ATLAS-772
Repository: atlas
Description
-------
When a schema query is issued against a hive table, the hive_column entities
are retrieved from the titan database. Each hive_column entity is a vertex in
titan and currently titan doesn't store any column order position in its vertex
attributes. The hive_columns are retrieved in the sort order of the Vertex ID
which is not same as the Hive column order position. The fix attached is to
introduce a new "position" attribute in hive_column type, which maintains the
column order position. This column order position can be consumed by any
clients - including UI to display the columns in the original position/order.
