cmapi packages with single node installation causes DBRM readonly error

Build tested: MCS 6.2.2, 6.3.1
cmapi: 1.5, 1.6
OS: I have been testing with Ubuntu 18.04.

For single node installation, cmapi package is installed, the node would end up in a DBRM readonly state. Starting the cmapi server or not does not make a difference.

The simplest way to reproduce this is to just install all the deb packages, then run DDL statements. DBRM readonly error will occur.

Although cmapi is not required for single-node installation, there is a high chance that user's would just install all packages download, causing this issue.

I did not see the same issue with multiple-node installation, which requires cmapi.

So far, I did the following columnstore and cmapi combinations:

6.2.2-1 1.4 single-node passed
6.2.2-1 1.4 multi-node passed

6.2.2-1 1.5 singl-enode failed
6.2.2-1 1.5 multi-node passed

6.3.1-1 1.5 single-node failed
6.3.1-1 1.5 multi-node passed

6.3.1-1 1.6 single-node failed
6.3.1-1 1.6 multi-node passed

The issue was not identified previously because for single-node installation, cmapi was not installed since it was not required.
