Description
To repro:
- setup single node cluster
- load travel-sample
- run following advisor session:
- SELECT ADVISOR({'action':'start', 'duration':'40m'})
- SELECT airportname FROM `travel-sample` WHERE type = "airport" AND lower(city) = "lyon" AND country = "France";
- select advisor({'action':'list'});
- select advisor({'action':'stop', 'session':'18a0a2d5-9750-4245-8415-447bff9c1322'}); – replace with your session-id
- select advisor({'action':'list'}) or select advisor({'action':'get', 'session':'18a0a2d5-9750-4245-8415-447bff9c1322'});
- select advisor({'action':'stop', 'session':'18a0a2d5-9750-4245-8415-447bff9c1322'}); – replace with your session-id
- select advisor({'action':'list'}) or select advisor({'action':'get', 'session':'18a0a2d5-9750-4245-8415-447bff9c1322'});
with the second stop the session info is purge:
