Subject [jira] [Created] (AIRFLOW-1121) airflow webserver --pid no longer write out pid file!
Date Tue, 18 Apr 2017 21:40:41 GMT
Siddharth Anand created AIRFLOW-1121:
----------------------------------------

             Summary: airflow webserver --pid no longer write out pid file!
                 Key: AIRFLOW-1121
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1121
             Project: Apache Airflow
          Issue Type: Bug
          Components: webserver
    Affects Versions: 1.8.1rc0
            Reporter: Siddharth Anand
            Priority: Blocker


I've run into a regression with the webserver. It looks like the --pid argument is no longer
honored in 1.8.1. The pid file is not being written out! As a result, watchdog processes like
monitd, which watch the processes mentioned in the pid file, keep trying to spawn webservers
because the pid files are not being written.

HISTTIMEFORMAT="%d/%m/%y %T " PYTHONPATH=/usr/local/agari/ep-pipeline/production/current/analysis/cluster/:/usr/local/agari/ep-pipeline/production/current/analysis/lookups/
TMP=/data/tmp AIRFLOW_HOME=/data/airflow PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin
airflow webserver -p 8080  --pid /data/airflow/pids/airflow-webserver.pid

The Patch that might have broken this is 
https://github.com/apache/incubator-airflow/commit/a9b20a04

If I include -D, things work:
airflow webserver -D --pid ~/this.pid

sid-as-mbp:~ siddharth$ ls -lrt *pid
-rw-r--r--  1 siddharth  staff  5 Apr 18 14:37 this-monitor.pid
-rw-r--r--  1 siddharth  staff  5 Apr 18 14:37 this.pid
sid-as-mbp:~ siddharth$ cat *pid
8732
8735

However, this doesn't help me as I don't want to run with -D.
