Tip: The Restart Trifacta button in the Admin Settings page is the preferred method for restarting the platform.
NOTE: The restart button is not available when high availability is enabled for the Alteryx® node.
See Admin Settings Page in the Admin Guide.
NOTE: In an Azure HDI environment, you must perform platform start and stop operations from
/opt/trifacta. Running these commands from other directories, such as
/root, can cause service issues.
NOTE: These operations must be executed under the root user.
service trifacta start
Check logs for errors:
You can also access logs through the Designer Cloud® application for each service. See System Services and Logs in the Admin Guide.
Login to the Designer Cloud application. If available, perform a simple transformation operation. See Login.
Run a simple job. See Verify Operations in the Admin Guide.
service trifacta restart
When the login page is available, the system has been restarted. See Login.
service trifacta stop
You can verify operations of WebHDFS. Command:
curl -i "http://<hadoop_node>:<port_number>/webhdfs/v1/?op=LISTSTATUS&user.name=trifacta"
Error - "ImportError: No module named pkg_resources" error in supervisord
When you start the platform for the first time, you may receive the following error:
Traceback (most recent call last): File "/usr/local/bin/supervisord", line 5, in <module> from pkg_resources import load_entry_point ImportError: No module named pkg_resources
This error occurs when the supervisord process is starting. The Designer Cloud Powered by Trifacta platform fails to complete startup.
This issue is caused by a missing package for supervisord. The simplest solution is to install the Python setup tools on the Alteryx node. Commands are listed below.
NOTE: These commands must be executed as root user.
yum install python-setuptools
wget https://bootstrap.pypa.io/ez_setup.py -O - | python
After installation is complete, restart the platform.
Error - SequelizeConnectionRefusedError: connect ECONNREFUSED
If you have attempted to start the platform after an operating system reboot, you may receive the following error message, and the platform start fails to complete:
2016-10-04T14:03:17.883Z - error: [ENVIRONMENT] Environment Sanity Test Failed 2016-10-04T14:03:17.883Z - error: [ENVIRONMENT] Exception Type: Error 2016-10-04T14:03:17.883Z - error: [ENVIRONMENT] Exception Message: SequelizeConnectionRefusedError: connect ECONNREFUSED
NOTE: This solution applies to PostgreSQL 9.6 only. Please modify for your installed database version.
This error can occur when the operating system is restarted. Please execute the following commands to check the PostgreSQL configuration and restart the databases.
chkconfig postgresql-9.6 on
Then, restart the platform as normal.
service trifacta restart
