CarteTransOperator works incorrect when transformation failed

[evgdol]

Scenario (simplified)

1. We have the table in the database with constraints
   CREATE TABLE tst_constraints( id int PRIMARY KEY, val text )

2. We have the simple transformation that inserts the data into this table
   

3. Call the transformation in Airflow
   trans = CarteTransOperator( task_id='tst_trans_fail', pdi_conn_id='pentaho', trans='/public/test/tr_tst_failed_tab_constraint' )

Result

1. If table is empty (no constraints inconsistency) all works as expected
2. If the table contains inserted data, I have found two possible scenarios (the second is more often):
   2.1. The task finished with SUCCESS flag
   
   

2.2. The task freezing, but the transformation already failed.

Expected result

CarteTransOperator works properly

Additions

After discussion in Issue #29 :
If we wrap around the transformation in job, it works fine. But I want to know if it is possible to solve this issue without this.

Environment

Airflow 2.5.1 + Python 3.10 + Pentaho server CE 8.0

Not solved!

Sorry. Now it should work.

[evgdol]

Nothing changed. The result is the same as on previous my screenshot.

I have found the issue.
You should change the condition in WHILE:

There are FINISHED_STATUSES used in your code.
I have changed on my side and it works.

You are right @evgdol . I need to add some tests for this. But I'm about to release a version with this fix.
