Regarding scheduling the DAG with trigger_dag command
Hi, After reading the blog for Tips and Tricks of Airflow, i was trying my hands on trigger_dag run command. But this only creates an instance of dag with status running. But actually no task starts getting executed. Whereas with backfill, it schedules the dag there and then. How can i force the tasks of the dag to start via trigger_dag command? Regards, Twinkle
Re: Logging to postgres as super user
Hi,
I used the following code to do the bulk upload in postgres ( It does not
have any super user issue ):
def bulk_load(self, table, tmp_file):
"""
Loads a tab-delimited file into a database table
"""
conn = self.get_conn()
cur = conn.cursor()
sqlStr = "COPY " + table + " FROM STDIN"
with open(tmp_file) as f :
cur.copy_expert(sqlStr, f)
conn.commit()

Logging to postgres as super user
Hi,
I was trying to do bulk upload via postgres using it's copy command.
While doing so, i received message :
airflow/hooks/postgres_hook.py", line 58, in bulk_load
cur.execute("COPY %s FROM '%s'" % (table, tmp_file))
psycopg2.ProgrammingError: must be superuser to COPY to or from a file
HINT: Anyone can COPY to stdout or from stdin. psql's \copy command also
works for anyone.
While browsing, i got to know that i can use alter user command, to assign
superuser status to the current user.
While trying to execute that, i am receiving following error :
cur.execute("alter user smrt_repl_rt superuser;")
psycopg2.ProgrammingError: must be superuser to alter superusers
Is there a way, i can connect to database as super user via some other
arguments?

retry handler not getting called
Hi,
I am working with a hiveToMySql transfer operation, which is not able to
connect and gives following logs:
HiveServer2Error: Failed after retrying 3 times
[2016-10-27 01:54:46,524] {models.py:1298} INFO - Marking task as
UP_FOR_RETRY
As per the code in the models.py,
https://github.com/apache/incubator-airflow/blob/master/airflow/models.py#L1347
, it should be calling the code for retry handler ( we are using version
1.7.1.3), but it is not happening.
Here is the relevant code snippet:
def my_retry_handler(context):
print "my_retry_handler called" slack_retry_notification =
SlackAPIPostOperator( task_id='Slack_Failure_Notification',
token="XX",
channel='@yy',
text=":skull: - {time} - {dag} attempt has been failed
".format(dag='Some Dag',time=datetime.now().strftime("%Y-%m-%d %H:%M:%S"),
),
owner='Retry Handler')
return slack_retry_notification.execute
hiveToMySql = HiveToMYSQLTransfer(sql="jdbsd", hiveserver2_conn_id='
hiveserver2_default',.
on_retry_callback=my_retry_handler)
Is there something i am missing?

Regarding running of the task in airflow
Hi, I have scheduled a job at 3:00 a.m. daily. When i go the detailed view of the dag, i see the instance of the execution from the start date to yesterday only even if i am viewing it at 11:00 a.m. Any pointers? P.S: In the pitfalls document ( https://medium.com/handy-tech/airflow-tips-tricks-and-pitfalls-9ba53fba14eb#.x4jwbmw0b) , it has been mentioned that DAG execution happens at the day end and not at day start. Unfortunately, I am not able to relate with the issue i am facing. Regards, Twinkle

Re: Regarding force running the whole graph from UI
It is not triggering the rest of the graph. It leads to execution of first task only. Are there some other flags / Layout change which needs to be done?
