> I am trying to fetch column level lineage after a CTAS query in a Post Execution hook in Hive. Below are the queries:
> {code}
> create table t1(id int, name string);
> create table t2 as select * from t1;
> {code}
> The lineage information is retrieved using the following sample piece of code:
> {code}
> lInfo = hookContext.getLinfo()
> for(Map.Entry<LineageInfo.DependencyKey, LineageInfo.Dependency> e : lInfo.entrySet()) {
>     System.out.println("Col Lineage Key : " + e.getKey());
>     System.out.println("Col Lineage Value: " + e.getValue());
> }
> {code}
> The Dependency field(i.e Col Lineage Value)  is coming in as null.
