How 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="`;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="`;do export $line;done
                

For CDH parcel deployments:

• Run the interactive Hue Python shell (Ctrl+D to 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 password

  HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue changepassword admin

• Promote Hue user to superuser

  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
                

• List available subcommands

  HUE_IGNORE_PASSWORD_SCRIPT_ERRORS=1 /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue
