-----------------------------------
Summary: Lineage information not set properly
Key: HIVE-14706
URL: https://issues.apache.org/jira/browse/HIVE-14706
Project: Hive
Issue Type: Bug
Reporter: Vimal Sharma
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.
