Increasing timeout values for TestStandardProcessScheduler#validateEnabledDisableMultiThread
Increasing timeout for testConcurrencyWithEnablingReferencingServicesGraph as 10s is not sufficient for overly taxed environments.

NIFI-108: Implementing ability to list FlowFiles in a queue
NIFI-108:
- Starting to add support for endpoints that will listing flowfiles in a queue.
NIFI-108: Added merging of response for listing of flowfiles in cluster manager
NIFI-108:
- Starting to add support for endpoints that will listing flowfiles in a queue.
NIFI-108:
- Starting to add support for endpoints that will listing flowfiles in a queue.
NIFI-108:
- Adding checkstyle issues.
NIFI-108: Add clusterNodeId to FlowFileSummaryDTO
NIFI-108: Added unit tests; added verifyCanList method to queue; fixed bugs
NIFI-108:
- Adding compilation error for IOException from getFlowFile().
- Code clean up.
- Javadocs.
NIFI-108:
- Verifying two phase commit for queue listing.
- Fixing checkstyle.
- Ensuring drop and listing requests are merged when created when clustered.
NIFI-108:
- Adding initial listing capabilities.
- Passing through the sort column and direction.
NIFI-108:
- Removing Delete FlowFile button.
- Ensuring sort flags are being passed correctly.
- Setting column widths.
- Also including the cluster node address in the flowfile summaries.
NIFI-108:
- Including queue size statistics in listing request.
- Showing connection name.
NIFI-108:
- Including queue size statistics in listing request.
- Ensuring verifyCanList runs when appropriate.
NIFI-108:
- Adding initial support for viewing flowfile details dialog.
- Adding initial support for click to content.
NIFI-108:
- Allowing the flowfile details dialog to be draggable.
NIFI-108:
- Only showing the flowfile listing table when the listing is successful and the listing is not empty.
NIFI-108:
- Reseting the queue stats when closing the listing table.
NIFI-108: Implemented sorting when performing listing of FlowFiles
NIFI-108: Fixed bug that caused the listFlowFiles operation to wait on a readLock before returning and performing work asynchronously; fixed bug in Write-Ahead FlowFile Repository that caused ContentClaims to be queued up for destruction instead of ResourceClaims - this caused millions of ContentClaims to be queued up instead of a single ResourceClaim in some tests
NIFI-108:
- Ensured the column sort indicator is reset when a new listing is opened.
- Removing unused import.
NIFI-108:
- Addressed issues found during the review.
- Introduced nifi-riemann-bundle for future Riemann backed monitoring
- Added initial PutRiemann processor for writing events to Riemann
using the Riemann batch client.
- Values for events are provided using the NiFi expression language
e.g. Metric -> ${latency.milliseconds:divide(1000)}
Added isActive check to the StandardControllerServiceNode:280 to ensure that
the IF statement can only have a chance to succeed if service is active. The service
will be indiscriminately deactivated as soon as disable(..) operation is invoked. This itself will
eliminate the race condition discovered by Mark
NIFI-1164 addressed PR comments
fixed the race condition described by Mark during disable call
NIFI-1164 polished javadoc
Changed ControllerServiceNode by adding enable(..), disable(..) and isActive() operations. See javadocs for more details in both ControllerServiceNode and StandardControllerServiceNode
Refactored service enable/disable logic in StandardProcessScheduler and StandardControllerServiceNode . Below are some of the notes:
- No need for resetting class loader since its going to derive from the class loader of the service. In other words any classes that aren’t loaded and will be loaded within the scope of the already loaded service will be loaded by the class lower of that service
- No need to control 'scheduleState.isScheduled()’ since the logic has changed to use CAS operation on state update and the service state change is now atomic.
- Removed Thread.sleep(..) and while(true) loop in favor of rescheduling re-tries achieving better thread utilization since the thread that would normally block in Thread.sleep(..) is now reused.
- Added tests and validated that the race condition no longer happening
Added additional logic that allows the initiation of the service disabling while it is in ENABLING state. See javadoc of StandardProcessScheduler.enable/disable for more details.
