MADlib install-check is failing


  • Pivotal Greenplum (GPDB) 4.3.x
  • OS RHEL 6.x
  • MADlib 1.9


When running install-check after MADlib installation it keeps failing with following error messages in the log.

Error Message:

$ $GPHOME/madlib/bin/madpack install-check -p greenplum
TEST CASE RESULT|Module: utilities|text_utilities.sql_in|PASS|Time: 3085 milliseconds
madpack.py : ERROR : Failed executing /tmp/madlib.4NMtGk/utilities/test/path.sql_in.tmp

The MADlib install-check script is running based on the pre-defined values prepared for the test purpose. So theoretically when the test data become corrupt/altered for some reason this symptom can happen.


Uninstall and Reinstall theMADlib package so correct test scripts/data can be installed.
You can refer following link for uninstalling or reinstall of MADlibMadlib package: How to install or uninstall MADlib

Additional Information

Once MADlib package is installed successfully, you can find all test scripts & data from these directories -
