Running shell commands
You can run shell commands to administer Hue programmatically. For example, to reset the superuser password or to assign an LDAP user superuser permissions.
To run Hue shell commands:
-
Set
HUE_CONF_DIR
to the latest Hue process directory:export HUE_CONF_DIR="/var/run/cloudera-scm-agent/process/`ls -alrt /var/run/cloudera-scm-agent/process | grep HUE_SERVER | tail -1 | awk '{print $9}'`" echo $HUE_CONF_DIR
-
Set environment variables used to run the Hue
webserver:
- CentOS/RHEL:
for line in `strings /proc/$(lsof -i :8888|grep -m1 python|awk '{ print $2 }')/environ|egrep -v "^HOME=|^TERM=|^PWD=|^CLDR_JAVA_OPTS="`;do export $line;done
- Ubuntu:
for line in `strings /proc/$(lsof -i :8888|grep -m1 hue|awk '{ print $2 }')/environ|egrep -v "^HOME=|^TERM=|^PWD=|^CLDR_JAVA_OPTS="`;do export $line;done

quit)
HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue shell
Or with the database password:
HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 HUE_DATABASE_PASSWORD=<your db password> /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue shell
- Change a user

HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue changepassword admin
- Promote Hue user to

HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue shell
from django.contrib.auth.models import User a = User.objects.get(username='gwen') a.is_superuser = True a.save()
-
Count all of the documents of a certain user:
from django.contrib.auth.models import User from desktop.models import Document2 user=User.objects.get(username='demo') Document2.objects.documents(user=user).count() Out[X]: 1167
