The reporting task used to hold a single AtlasClientV2 instance
throughout its runtime starting from being started until being stopped.
If it is configured to use Kerberos authentication for Atlas REST API, after
a published DelegationToken expires (10 hours by default), the reporting
task will not be able to recover from 401 Unauthorized state.
In order to avoid stucking in such situation, this commit changes the
way ReportLineageToAtlas uses AtlasClientV2 instance to create an
instance per onTrigger execution. It also addresses Kerberos ticket
expiration.
This approach incurs some overheads by initiating the client each time,
however, it should be insignificant from an overall processing time
perspective including analyzing NiFi flow and Provenance records.
- Simplified consumeEvents method signature
- Refactored ComponentMapHolder methods visibility
- Renamed componentMap to componentNameMap
- Map more metadata from ConnectionStatus for Remote Input/Output Ports
- Support Process Group hierachy filtering
- Throw an exception when the reporting task fails to send provenance
data to keep current provenance event index so that events can be
consumed again
