Kengo Seki commented on AIRFLOW-1121: ------------------------------------- Yeah, that's my fault. I mistakenly assumed that pid file is unnecessary if webserver runs in the foreground. Thanks for the notification Sid, I'll submit a PR today if possible. > 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 > Fix For: 1.8.1 > > > 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. > cc [~sekikn] [~criccomini] -- This message was sent by Atlassian JIRA (v6.3.15#6346)
