METRON-1674: Create REST endpoint for job status abstraction ## Contributor Comments This PR is built on top of https://github.com/apache/metron/pull/1108 and should be merged and final review done after that is accepted into the feature branch. This exposes the job manager and job status abstraction through a REST endpoint. A summary of the changes included: - Adjustments to the existing PcapService to accommodate the new JobManager abstraction - JobManager is now a Spring bean and job submission/status is done through that - New properties were added to application.yml and PcapServiceImpl - PcapJobSupplier was added that allows switching to a mock pcap job during integration testing - Unit and integration tests were adjusted to match - Time parameters are now `startTimeMs` and `endTimeMs` - FixedPcapRequest now matches the pattern used in PcapRequest - Addition of a PcapStatus object to return status in a simple, consumable structure for the UI - Endpoint to get job status was added - ConfigOption was adjusted to automatically handle type conversions in cases where Jackson deserialization is used (Integer to Long for example) - InMemoryJobManager now throws a JobNotFoundException when jobs don't exist for a username/job id combination - PcapJob will automatically convert PcapOptions.START_TIME_MS to PcapOptions.START_TIME_NS when START_TIME_NS is not set (same goes for END_TIME_NS) - New unit and integration tests added for get status endpoint and service This has been lightly tested in full dev. The HDFS paths must be created manually for the paths specified in application.yml. For now and only job submission and subsequent status retrieval had been tested. This PR should strictly be used for testing at this point. To test in full dev, create the HDFS directories mentioned above and put pcap data in `/apps/metron/pcap/input`. Submit a fixed pcap query: ``` curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{ "endTime": 1458240269424, "startTime": 1458240269419 }' 'http://node1:8082/api/v1/pcap/fixed' ``` A job id should be returned in the response: ``` { "jobId": "job_1531258337010_0021", "jobStatus": "RUNNING", "description": "map: 0.0%, reduce: 0.0%", "percentComplete": 0, "size": 0 } ``` Job status can now be retrieved using the get job status endpoint: ``` curl -X GET --header 'Accept: application/json' 'http://node1:8082/api/v1/pcap/job_1531258337010_0021' ``` A full, comprehensive review should be done after https://github.com/apache/metron/pull/1108 has been merged. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
