columnstoreDBWrite -c suspend fails if there are writes to the system

Executing `columnstoreDBWrite -c suspend` to a ColumnStore system which is still executing writes doesn't succeed. The return code of the program further doesn't indicate the failure.

[root@dbaas-1633-mdb-cs-single-0 /]# columnstoreDBWrite -c suspend

The following tables are locked:

LockID Name         Process  PID  Session  CreationTime           State    DBRoots

10     test.tmp2    cpimport 4414 BulkLoad 2020-02-17 01:33:37 PM LOADING  1

[root@dbaas-1633-mdb-cs-single-0 /]# echo $?

0

It would be better if `columnstoreDBWrite -c suspend` either

• forces the write only mode (by killing the active queries), or if it
• blocks all further write queries, waits until the active write queries are finished, and then puts ColumnStore into read only mode.

In case of an error, I would further expect a return code unequal to 0.
