Due to the fact that current component uses artificial names for properties set via UI and then maps those properties to the actual names used by Kafka, we can not rely on NiFi UI to display an error if user attempts to set a dynamic property which will eventually map to the same Kafka property. So, I’ve decided that any dynamic property will simply override an existing property with WARNING message displayed. It is actually consistent with how Kafka does it and displayed the overrides in the console. Updated the relevant annotation description.
It is also worth to mentioned that current code was using an old property from Kafka 0.7 (“zk.connectiontimeout.ms”) which is no longer present in Kafka 0.8 (WARN Timer-Driven Process Thread-7 utils.VerifiableProperties:83 - Property zk.connectiontimeout.ms is not valid). The add/override strategy would provide for more flexibility when dealing with Kafka volatile configuration until things will settle down and we can get some sensible defaults in place.
While doing it addressed the following issues that were discovered while making modification and testing:
ISSUE: When GetKafka started and there are no messages in Kafka topic the onTrigger(..) method would block due to the fact that Kafka’s ConsumerIterator.hasNext() blocks. When attempt was made to stop GetKafka would stops successfully due to the interrupt. However in UI it would appear as ERROR based on the fact that InterruptException was not handled.
RESOLUTION: After discussing it with @markap14 the the general desire is to let the task exit as quick as possible and that the whole thread maintenance logic was there initially due to the fact that there was no way to tell Kafka consumer to return immediately if there are no events. In this patch we are now using ‘consumer.timeout.ms’ property of Kafka and setting its value to 1 millisecond (default is -1 - always block infinitely). This ensures that tasks that attempted to read an empty topic will exit immediately just to be rescheduled by NiFi based on user configurations.
ISSUE: Kafka would not release FlowFile with events if it didn’t have enough to complete the batch since it would block waiting for more messages (based on the blocking issue described above).
RESOLUTION: The invocation of hasNext() results in Kafka’s ConsumerTimeoutException which is handled in the catch block where the FlowFile with partial batch will be released to success. Not sure if we need to put a WARN message. In fact in my opinion we should not as it may create unnecessary confusion.
ISSUE: When configuring a consumer for topic and specifying multiple concurrent consumers in ‘topicCountMap’ based on 'context.getMaxConcurrentTasks()’ each consumer would bind to a topic partition. If you have less partitions then the value returned by 'context.getMaxConcurrentTasks()’ you would essentially allocate Kafka resources that would never get a chance to receive a single message (see more here https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example).
RESOLUTION: Logic was added to determine the amount of partitions for a topic and in the event where 'context.getMaxConcurrentTasks()’ value is greater than the amount of partitions, the partition count will be used to when creating ‘topicCountMap’ and WARNING message will be displayed)see code). Unfortunately we can’t do anything with the actual tasks, but based on current state of the code they will exit immediately just to be rescheduled where the process will repeat. NOTE: That is not ideal as it will be rescheduling tasks that will never have a chance to do anything, but at least it could be fixed on the user side after reading the warning message.

Current implementation of DBCPConnectionPool was attempting to test if connection could be obtained via dataSource.getConnection().
Such call is naturally a blocking call and the duration of the block is dependent on driver implementation. Some drivers (e.g., Phoenix - https://phoenix.apache.org/installation.html)
attempts numerous retries before failing creating a deadlock when attempt was made to disable DBCPConnectionPool which was still being enabled.
This fix removes the connection test from DBCPConnectionPool.onConfigured() operation returning successfully upon creation of DataSource.

writing every Object to a new line, or as an array of Objects.
Let's assume you have an Avro content as stream of records (record1, record2, ...). If JSON container is "none", the converter will expose the records as sequence of
single JSON objects:
record1
record2
...
recordN
Please bear in mind, that the final output is not a valid JSON content. You can then forward this content e.g. to Kafka, where every record will be a single Kafka message.
If JSON container is "array", the output looks like this:
[record1,record2,...,recordN]
It is useful when you want to convert your Avro content to a valid JSON array.

Closes InputStreams created to read the public keys for PGP encryption and several other
streams involved in PGP encryptiong. This prevents NiFi from leaking file handles on
every validate call or encryption attempt in the EncryptContent processor.
Before this change, the host given out to clients to connect to a Remote
Process Group Input Port is the host where the NiFi instance runs.
However, sometimes the binding host is different from the host that
clients connect to. For example, when a NiFi instance runs inside a
Docker container, a client on a separate machine must connect to the
Docker host which forwards the connection to the container.
Add a configuration property to specify the host name to give out to
clients to connect to a Remote Process Group Input Port. If the property
is not configured, then give out the name of host running the NiFi
instance.
