Hot Fix 6.2.2 for SAS Event Stream Processing addresses the following issues:

Fixes:

• The Java SSL-enabled clients now import all certificates in a ca.pem file.
• In PI Web connector/adapter publisher, when there is a value type mismatch and "Good" = false, it does the following:
  • gives a log warning instead of an error
  • writes a null datavar
  • continues processing
• In the Kinesis connector/adapter publisher, fixed the retry logic for GetRecords() failures.
• Fixed an issue with stopping the Kinesis publisher connector/adapter when the connector/adapter handles multiple shards and is configured for the JSON, Avro, or protobuf formats.
• For the MQTT connector/adapter, changed the mqttclientid parameter from required to optional to fix the handling of a null client ID.
• Removed the Twitter and Twitter Gnip adapters.
• For the Kafka and Kinesis subscriber connectors/adapters that write Avro, now ignores a delete event following an updateblock event.
• Fixed an issue in the router when using the writer destination.
• In the Kafka connector/adapter, fixed corruption of the avroschemaname configuration parameter value.
• Fixed a lack of responsiveness that stops the Kinesis connector/adapter.
• Fixed a lack of responsiveness when a connector is throttled.
• Now allows only adapter connectors to run code in the bin directory of the SAS Event Stream Processor home directory (DFESP_HOME).  
• Fixed a lack of responsiveness in the adapter connector when a project is stopped via the REST application programming interface (API).
• Fixed an issue in the URL connector and the dfesp_xml_client when using an OpenResty/Nginx proxy.
• Fixed an issue in which the aggregate window is not defined with at least one key.
• Fixed an issue in the OPCUA connector when it stops after failing to connect to the OPCUA server.
• Fixed a Solace connector/adapter issue in which the publisher ignores the first message in a Solace queue.
• In the PI Web connector/adapter, fixed the authorization header when writing to PI using Basic or Bearer authentication.
