-------------------------------------------------------
Commit 2d03489ec5dbc56bcb0dbd7b694cdf030d2532a5 in nifi's branch
refs/heads/master from [~ozhurakousky]
[ https://git-wip-us.apache.org/repos/asf?p=nifi.git;h=2d03489 ]
NIFI-1296, NIFI-1680, NIFI-1764, NIFI-1837, NIFI-1827, NIFI-1699 implemented
new Kafka processors that leverage Kafka 0.9 API
- Improved StreamScanner for better performance
- Renamed StreamScanner to StreamDemarcator as suggested by Joe
- Added failure handling logic to ensure both processors can be reset to their
initial state (as if they were just started)
- Provided comprehensive test suite to validate various aspects of both Publish
and Consume from Kafka
- Added relevant javadocs
- Added initial additionalDetails docs
- Addressed NPE reported by NIFI-1764
- Life-cycle refactoring for the existing PutKafka to ensure producer restart
after errors
- Incorporated code changes contributed by Ralph Perko (see NIFI-1837)
- Addressed partition issue in RoundRobinPartitioner discussed in NIFI-1827
- Updated PropertyDescriptor descriptions to reflect their purpose
NIFI-1296 added @Ignore on some Kafka tests to improve test time
NIFI-1296 reworked tests to avoid dependency on embedded Kafka
NIFI-1296 fixed spelling error
NIFI-1296 fixed trailing whitespaces in non-java files
This closes #366
> NullPointerException in PutKafka for failed segments with no delimiter and
> insufficient producer handling

>
> This NPE can happen during certain failure cases and it appears to be related
> to the lack of guarding of the failed segments attribute addition in the case
> there is no delimiter. Further, we have observed the PutKafka processor
> becoming ineffective if the established kafka client starts seeing failed
> acks/timeouts. We need to catch those cases and teardown the old client and
> create a new one instead.
