--------------------------------
Summary: AWS DynamoDB Processors Do Not Update Credentials
Key: NIFI-2948
URL: https://issues.apache.org/jira/browse/NIFI-2948
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.7.0, 1.0.0
Reporter: James Wing
Priority: Minor
Following a report to the dev email list, there appears to be a bug in the AWS
DynamoDB processors where the AWS credentials are cached by the processor once
started, and not updated even if the processor is stopped, reconfigured, and
started.
The problem appears to be
[AbstractDynamoDBProcessor::getDynamoDB|https://github.com/apache/nifi/blob/rel/nifi-1.0.0/nifi-nar-bundles/nifi-aws-bundle/nifi-aws-processors/src/main/java/org/apache/nifi/processors/aws/dynamodb/AbstractDynamoDBProcessor.java#L218],
which assigns the dynamo client object to a class variable only once.
*Repro Steps*
# Add GetDynamoDB processor
# Configure GetDynamoDB required properties but *not* any credential fields
# Start the processor
# Run a flowfile through - it should fail with
"MissingAuthenticationTokenException" error
# Stop the GetDynamoDB processor
# Configure valid AWS credentials
# Start the processor
# Run a flowfile through - it should fail again with
"MissingAuthenticationTokenException" still using the old credentials
