Troubleshooting
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.
Solution:
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.
CentOS/RHEL:
yum install python-setuptools
Ubuntu:
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
Solution:
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
