Fredrik Sko updated NIFI-4629:
------------------------------
Description:
When using the ControlRate processor, defining the "Grouping Attribute" with a
missing/non-existing attribute name produces NullPointerException errors.
Processor configuration:
{quote}
Rate Control Criteria: flowfile count
Maximum rate: 10
Rate Controlled Attributes: (No value set)
Time Duration: 1 min
Grouping Attribute: foobar
{quote}
ControlRate with the following configuration when sent a flowfile without the
attribute {{foobar}} generates the following error:
bq. ControlRate\[id=dff05b32-015f-1000-db55-5957a9298bab]
ControlRate\[id=dff05b32-015f-1000-db55-5957a9298bab] failed to process due to
java.lang.NullPointerException; rolling back session: null
Additionally, the incoming flowfiles now ends up in some "dead" state where I'm
unable to even empty the queue.
A simple template for reproduction is attached.
