Improvements and Behavioral changes

Learn about the change in certain functionality of Flink and Cloudera SQL Stream Builder that has resulted in a change in behavior from the previously released version of Cloudera Streaming Analytics.

Improvements

Replaced the bahir-flink Kudu connector with the externalized flink-connector-kudu

The new Kudu connector is updated to the current Flink APIs, and also includes new features.

Highlights:

Updated existing Table API stack, and DataStream Sink code
Source API implementation that includes streaming mode support
SQL option to configure Kudu FlushMode
PRIMARY KEY definition as part of the SQL code

To see all the included changes and learn more about the Kudu connector, see the Apache release notes.

Added aes256-cts-hmac-sha1-96 enctype as default to Keytab service

The keytab generation through Cloudera SQL Stream Builder works out of the box in environments where the Kerberos environment is configured to use the aes256-cts encryption type.

Unified default Flink job log4j rolling configuration

For jobs deployed through both Cloudera SQL Stream Builder and Flink, the log4j configuration now by default:

Applies compression
Keeps the last 5 entries
Triggers rollover when size reaches 100MB

For more information on configuring logging, see Adjusting logging configuration in Advanced Settings.

Added metric reporter jars to parcel

All metrics reporter implementations available in the core vanilla Flink distribution are shipped with Cloudera Streaming Analytics. Customers can use them by modifying flink-conf.yaml. For more information, refer to Metric Reporters in the Apache Flink documentation.

Enhanced Python editor in the UI

The code editor in Cloudera SQL Stream Builder UI is extended for better Python syntax checking and codestyle support.

Refactored schema detect UX for Kafka wizard tables

Users can refresh the detected schema using the UI. The new Avro schema is displayed after the new detection was successful.
