Problem
Snapshot import remains stuck in “Import in progress” state even though no import activity
Solution
Have added PID check to see if there was any interruption to the process. If yes will report that as failure.

{

    "status": "Failed",

    "message": "Import operation was interrupted (system reboot or process termination)"

}
{

    "status": "Failed",

    "message": "Export operation was interrupted (system reboot or process termination)"

}
