 Description   

Exiting from the process doesn't work properly.
1. User starts the process.
2. User wants to finish the process with CTRL+C

Result:
Message "Shutting down..." is displayed and it stays forever.
Only way to exit the process is to kill it.
Also killing the process leaves table locked by mcsapi and table can't be deleted or truncated.

Expected:
Process must shut down properly and release the table lock.

The Shutting down... message tells that the adapter is trying to do a controlled shutdown. The program should exit the next time the CDC connector returns a timeout error.

What is the exact command line used in this case?

mxs_adapter -c /etc/Columnstore.xml -u cdcuser -p cdcpassword -h localhost -P 4001 cdc_eli bst

It never finished. At least in observed time. No idea how long to wait for timeout.

Does it work if you add the -t 5 option? If it does, I think it might be a bug caused by commit 5ed54d5f839442c17ad0b7aa5c9ea9ef3728ee17.
