Koji Kawamura 4b8c80cccc NIFI-4741: Avoid DelegationToken expiration at ReportLineageToAtlas. This closes #2377 ... 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.		2018-01-05 11:17:33 -05:00
