-----------------------------------------
Summary: Validate operator IDs so that they don't contain special
characters and spaces
Key: SAMZA-1501
URL: https://issues.apache.org/jira/browse/SAMZA-1501
Project: Samza
Issue Type: Task
Reporter: Prateek Maheshwari
Assignee: Prateek Maheshwari
Since user provided operator IDs are also used as changelog stream names, we
should validate that they don't contain special characters and spaces.
If Kafka is used for the changelog topic, it'll fail with an exception like the
following:
{code}
2017-11-14 11:45:14.408 [main] KafkaSystemAdmin [WARN] Failed to create topic
wikipedia-application-1-window-Tumbling window of WikipediaStats:
org.apache.kafka.common.errors.InvalidTopicException: topic name
wikipedia-application-1-window-Tumbling window of WikipediaStats is illegal,
contains a character other than ASCII alphanumerics, '.', '_' and '-'. Retrying.
