Environment

GPDB 5.28.2

GPCC: 6.11

Cause

User input value is expected to be record in app.conf as:

krb_libpath='xxx'

However, it's recorded as:

libpath='xxx'

This causes issues with Go, not being able to locate the required library and/or socket files

Resolution

Issue is fixed as of GPCC 6.12.0. As a work around, locate app.conf at "greenplum-cc-HOME_DIRECTORY/greenplum-cc-x.x.0/conf/app.conf" and change the key "libpath" to krb_libpath"

Additional Information

Issue is fixed as of GPCC 6.12.0
