Shalin Shekhar Mangar updated SOLR-11085:
-----------------------------------------
Attachment: SOLR-11085.patch
This patch:
# Passes ZkController to the TriggerFactory to avoid running into SOLR-11370.
Similarily, triggers use the ZkController directly instead of accessing it via
container.getZkController.
# ExecutePlanAction always calls collection APIs in async mode and uses the
request id to poll for completion of tasks.
# Fixes a bug in Preference where the setApproxVal method was trying to access
metrics for non-live nodes leading to NPE.
# ScheduledTriggers:
## adds more protection against overseer shutdown
## ScheduledTriggers fires listeners for event stage STARTED after the event is
enqueued successfully to ZK
## ScheduledTriggers waits for pending tasks requested by ExecutePlanAction
before trying to compute/execute the plan again
# SharedFSAutoReplicaFailoverTest now restarts overseer sometimes and removes
the nocommit added by SOLR-10397
> Improve resiliency of autoscaling actions
