Subject [jira] [Commented] (AIRFLOW-1153) params in HiveOperator constructor can't be passed into Hive execution context
Date Mon, 23 Apr 2018 16:57:00 GMT

    [ https://issues.apache.org/jira/browse/AIRFLOW-1153?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16448437#comment-16448437

ASF subversion and git services commented on AIRFLOW-1153:
----------------------------------------------------------

Commit 09bbe247728993867c716635951219cc49f65dd1 in incubator-airflow's branch refs/heads/master
from Alan Ma
[ https://git-wip-us.apache.org/repos/asf?p=incubator-airflow.git;h=09bbe24 ]

[AIRFLOW-1153] Allow HiveOperators to take hiveconfs

HiveOperator can only replace variables via jinja
and the replacements
are global to the dag through the context and
user_defined_macros.
It would be much more flexible to open up
hive_conf to the HiveOperator
level so hive scripts can be recycled at the task
level, leveraging
HiveHook already existing hive_conf param and
_prepare_hiveconf
function.

Closes #3136 from wolfier/AIRFLOW-1153

>             select * from t1 where t1.x > ' ${hiveconf:mynumber}'
>         ''',
>         params={'mynumber': 2},
>         dag=dag
