Clickstream Demo: Recovering from install errors

[hjafarpour]

@alexhafner the first failure corrupted the environment since and you could not recover from it. There are few options to clean up your environment and try again.

• You can destroy the confluent platform and restart it again. This way you will have a clean env and you can start the demo.
• You can delete 'ksql__commands' topic in kafka along with the other topics and start again.
  If non of these work please let me know.

I went down the second route to test if we can recover without a full destroy.

One extra step was needed, as the _TS topics autocreate themselves again on deletion.

This is due to the Kafka Connectors, which I've removed using the REST api

curl -X DELETE localhost:8083/connectors/es_sink_EVENTS_PER_MIN_MAX_AVG_TS curl -X DELETE localhost:8083/connectors/es_sink_CLICKSTREAM_STATUS_CODES_TS curl -X DELETE localhost:8083/connectors/es_sink_ENRICHED_ERROR_CODES_TS curl -X DELETE localhost:8083/connectors/es_sink_CLICK_USER_SESSIONS_TS curl -X DELETE localhost:8083/connectors/es_sink_USER_IP_ACTIVITY_TS curl -X DELETE localhost:8083/connectors/es_sink_PAGES_PER_MIN_TS curl -X DELETE localhost:8083/connectors/es_sink_ERRORS_PER_MIN_TS curl -X DELETE localhost:8083/connectors/es_sink_ERRORS_PER_MIN_ALERT_TS curl -X DELETE localhost:8083/connectors/es_sink_EVENTS_PER_MIN_TS
After that, all relevant topics could be deleted and the install restarted. The install completed perfectly. Many thanks @hjafarpour !
