Summary: Hive hook with V2 notifications - incorrect handling of
'alter view as' operation
Key: ATLAS-2524
URL: https://issues.apache.org/jira/browse/ATLAS-2524
Project: Atlas
Issue Type: Bug
Components: atlas-intg
Affects Versions: 1.0.0, 0.8.3
Reporter: Madhan Neethiraj
Assignee: Madhan Neethiraj
After recent update of Hive hook, to replace use of V1 notifications with V2
notifications (ATLAS-2491), 'alter view as' operation results in incorrect
metadata update. Consider the following Hive statements which create a view and
followed by an alter view:
{code}
create table table1(col1 int, col2 string);
create table table2(col3 date , col4 string);
create view view1 as select * from table1;
alter view view1 as select * from table2;
{code}
With earlier Hive hook implementation, after "alter view as", 'view1' would
have columns col1 and col2 as DELETED and col3, col4 as ACTIVE.
After update in ATLAS-2491, view1 continues to show col1 and col2 in ACTIVE
state; and doesn't have col3 and col4 columns.
