The list of supported CentOS versions for CDH clusters managed by Cloudera Altus Director 2.8 and 6.0 do not include CentOS 7.6, however we have several clusters managed by Director 2.8 running CentOS 7.6.
Support for CentOS 7.6 was added in Cloudera Altus Director 6.2, which released today. Altus Director does not validate the CentOS version, but CentOS 7.6 has not been tested with older Altus Director versions.
